The Adobe PDF Settings page shows the conversion settings that you can specify for your sources to use. You can use any of the predefined PDF settings or create your own. The PDF settings determine precisely how files are. This has been puzzling me for a few days now, and I asked a graphic designer I knew before trying here and haven't been able to solve it yet. It's quite weird so please bear with me for a bit. I am using Adobe Illustrator to. Raise Image Resolution Directly in In. Design[Editor's note: This is an article submitted for your enjoyment by In. Design expert Branislav Milic, who runs a wonderful French- language In. Design site. It's an interesting technique that reveals a fascinating and rarely explored aspect of the transparency flattener.]It is sometimes difficult for users to foresee image resolution and dimensions they will need while they are laying out an In. Design document, and it is particularly difficult to set the images' output resolution to 3. Very often, some images, due to numerous scalings up and down during the layout, have an effective resolution of less than 3. PDF- -a quality that you usually accept. Learn how to save or export Adobe Photoshop files to a variety of different image or graphics formats.Measuring DPI with a Ruler. One of the most confusing aspects of DPI is figuring out how big something is based on it’s resolution when it comes time to printing. The rule of thumb here is that 1 inch = 72 DPI. Well, sort of. If you’re an After Effects fan, you should check out the After Effects World Conference. It’s being held in Seattle this week. Several members of the Adobe team as well as top gurus speaking at the conference. I'll be there. However, when the PDF is received by the prepress operator of a newspaper or a magazine, it is typically checked in a preflight tool such as Enfocus Pit. Stop or Adobe Acrobat Pro - - which will warn that the resolution of some images is not 3. The result:  the operator too- often sends the PDF back to its creator. So, how to fix the resolution without opening each image in Photoshop, especially when there are dozens or even hundreds of images involved? Very simple.. just force In. Design to raise the resolution to 3. Here's how to do it. In Photoshop, create a document with the following specifications: The dimensions must be the same as the In. Design document. Also pay respect to the orientation of the In. Design document. If it is oriented in Portrait mode, do the same in the Photoshop file. Set the Resolution to 3. Set the Color Mode to CMYK. In Background Contents, fill the Photoshop file with a white background. In fact the type of file, the fact that it is flattened or layered does not matter at all. Save the file. It can be a JPEG, but do not include any ICC profile. Name the document something like "White Background. One way to describe an image using numbers is to declare its contents using position and size of geometric forms and shapes like lines, curves, rectangles and circles; such images are called vector images. .the documents raster effects resolution is required for effects applied in illustrator). Raster effects are effects that generate pixels, rather than vector data. Raster effects include SVG Filters, all of the effects in. For more information on transparency output issues, see the Print Service Provider Resources page of the Adobe Solutions Network (ASN) (English only), available on the Adobe website. Thanks for coming to InDesignSecrets.com, the world's #1 resource for all things InDesign! In your In. Design document, it is important that the images and the texts are wisely distributed among layers. All the images should have been placed on the "Images" layer, and all the texts should have been placed on the "Text" layer. I recommend that the "Text" layer is placed above the images, and more specifically above all the other objects using transparency options (opacity of less than 1. Jump to a master page that has an influence on all the other document or master pages. Create a layer called something like "Resolution" that you will position above the "Images" layer but beneath the "Texts" layer! On that master page and on that layer, import the "White Background. In. Design document. If the document has been created with a master page having an influence on all the other master pages, all the images of the document will now suddenly be hidden. If some images are still visible, this means that some master pages are independent. Thus place the "White Background. Using the Selection Tool (Black Arrow), select the graphic frame that contains the "White Background. Multiply" in the Effects panel. Now all the document's pages display properly again. What you have done here is placed a 3. When the transparency flattener will blend the images, it will use the resolution of the highest image file in the pile and will blend all the images at its resolution - - thus 3. For example, in the image below, I have placed a 7. White Background. This screenshot is slightly scaled down so its resolution is increased up to 9. Export the In. Design document as a PDF (or create a Post. Script file that you will place into the Distiller) and choose the PDF- X/1a: 2. Acrobat 4, PDF 1. Open the resulting PDF in Adobe Acrobat Pro. Choose Advanced > Print Production > Preflight. Among the three little squares on top of the palette, select the one in the middle "Select Single Checks". In the list of presets, select the one in the Images section named Resolution of color and grayscale images is greater than 2. Select and double- click this preset or click the "Analyze" button in the lower right corner: you'll notice that Acrobat displays a warning. Click on the little gray arrow next to the red cross to reveal the list of images and you will notice that they all have a resolution of 3. There appear to be a lot of images because the transparency flattener has created a jigsaw- puzzle of flattened and contiguous images that have no influence on the texts and vector shapes above. Note #1: if you want to increase the resolution from 3. White Background. Photoshop and increase its resolution to 4. Image menu > Image Size). Save the file, go back to In. Design and update the link. Re- export and enjoy this trick! Note #2: To scale images, In. Design uses the legendary Bicubic Interpolation Algorithm that has been present in Adobe software for years. We can thus expect a very good resampling quality. Remember: this trick is only really intended to fool the preflight tools when you're too lazy to adjust the effective/output resolution of each image in Photoshop. Note #3: If you are working in a unflattened workflow (Acrobat 5 - PDF 1. Adobe Certified RIP or manually via the "Control Flattener Setting" on the Preflight panel (in Acrobat). Note #4: Zevrix's Link Optimizer for In. Design is a fantastic utility to control the output resolution of images in In. Design document (and other image formatting changes).

Design and Convert to CMYK On Export[This article was co- authored by Claudia Mc. Cue and David Blatner.]Yes, we know you probably learned to convert images to CMYK in Photoshop before placing them in In. Design. And yes, we know that youâve been doing this since 1. Page. Maker 2. But you know what? This is the 2. 1st century now and itâs time to wake up, smell the coffee, and change your ways for the better. So, even though weâve been saying this for 1. You can leave your images in RGB. You donât need to convert them to CMYK. And in fact, you probably should not convert them to CMYK (at least not in Photoshop). As we have traveled around the world giving presentations about In. Design, Photoshop, and publishing, weâve been constantly amazed at the number of people who are still using the old, 2. CMYKâ workflow. And we feel a bit like someone walking into a jail announcing, "Hey, the doors aren't locked! You don't have to stay in here!" Some people immediately jump up and taste freedom; some wake up to the new realization slowly; and others refuse to believe it, knowing that staying behind bars is more comfortable than facing the unknown. True, in Ye Olden Days, the RIPs (Raster Image Processors) used by commercial printers to translate Post. Script from graphics programs did a lousy job of converting RGB to CMYK, resulting in muddy, inaccurate color rendering. Thus it was that, in all the land, a decree went out, ordering that Thou Shalt Convert Thy RGB Images To CMYK Before Sending Thy Job To The Printer. Fast forward to Modern times: Current print workflows perform excellent conversions of RGB to CMYK, and some printing processes â such as digital presses and large- format inkjet output â actually provide better and more vibrant output when fed with RGB content. Youâll still encounter print providers who insist on the submission of CMYK content, partly because âthatâs how weâve always done itâ (and partly because some very small shops might still be using antiquated equipment). Of course, you should always consult the printer to determine how your job should be submitted â never assume! But here's the truth: In. Design can convert your images to CMYK as well as Photoshop can. It uses the same color engine, so you can get exactly the same results. There are a few, relatively rare exceptions to this rule, which weâll cover below.)So now, in the 2. Keep your images in RGB as long as you can, place them, as RGB, into In. Design⦠and then, only if you have to, convert to CMYK inside In. Design when you make your PDF files. We're Talking Pixels Here. We want to be clear that weâre talking about pixel- based images here - - bitmapped images, such as those from Photoshop. Weâre not talking about vector artwork. In. Design can convert RGB vector artwork, too, but it won't necessarily end up the way you'd expect. If you're using Illustrator or a similar vector- drawing tool to make logos or illustrations that will likely be printed, we generally recommend using CMYK or spot colors, not RGB. Similarly, when you're applying solid colors to objects in In. Designâand those documents are headed for printâyou should use CMYK or spot color swatches, not RGB, in the interest of predictable conversion. For example, if you apply a solid RGB color 0/2. Instead, youâll get something like 5. Thatâs just par for the course when it comes to converting solid RGB colors to CMYK. So if you want 1. In. Design as 1. 00% cyan. Tip: In the Swatch Options dialog box, In. Design and Illustrator both warn you if an RGB color falls outside what CMYK printing inks can reproduce (called the CMYK âgamutâ). Click the yellow alert triangle to convert to the closest in- gamut RGB value, so you wonât be shocked when the color is converted to CMYK. Note that weâre emphasizing âfor print.â If youâre creating documents that are primarily for on- screen viewing, then solid RGB colors are great, even in vector artwork! Why Placing RGB Images is (better than) OKWhatâs so wonderful about Red- Green- Blue? RGB is the native language of digital cameras and scanners, and it can faithfully portray a wide range (gamut) of colors, from vibrant oranges to brilliant greens, from bright white to dramatic black. Cyan, magenta, yellow, and black (CMYK) printing inks can render a smaller range of colors, resulting in disappointing approximations of those oranges and greens, as well as other commonly desired colors, such as navy blue. When you convert RGB images to CMYK, you lose those out- of- gamut colors, and they wonât come return if you convert back to RGB. But hereâs the important part: Just because you place RGB images into In. Design doesnât mean youâre sending RGB images to your printer! In. Design can convert those RGB images to CMYK when you export your PDF file. It changes them in the PDF file without modifying your originals on disk.) So by placing RGB images, you have a choice: send RGB or CMYKâand if you choose CMYK, then you have to decide which CMYK. The âwhich CMYKâ is a new question for a lot of people, because they think thereâs just one CMYK. But there are thousands of different CMYKs! So when you convert an RGB image to CMYK in Photoshop youâre targeting (optimizing for) just one of those. And, unless you use the correct target printing profile to perform the conversion, you may have stripped out RGB colors that could have printed successfully. For example, if you used a profile for uncoated paper when preparing images that will print on coated stock, your conversion is way off. Plus, printers who have implemented a full color- managed workflow want your images as RGB because they can convert to CMYK at the last stage before printing, optimizing output for the final printing platform. Even better, sticking with RGB means you can use the same images for different jobs: the same document could be printed on Web press coated paper one day and then sheetfed uncoated paper the next. Or you can use the same image assets in multiple waysâ for example, a brochure printed on a sheetfed offset press, and a companion banner printed on a grand format inkjet device. The results might be very slightly different, but you will be able to get the best quality from each, rather than target just one printing condition and then leave the other one to chance. Keep in mind that most modern printers can handle RGB content. Converting to CMYK early wonât necessarily ruin the outcome, but might result in the loss of some color gamut, especially if the job is going on a digital press such as the HP Indigo or a wide- gamut device such as a large format inkjet printer. So talk with your printer: If they say they can accept a PDF/X3 or PDF/X4 file, that means they can handle the conversion from RGB to CMYK themselves (and, again, theyâll probably do a better job of it than you can). If they say they need all your images converted to CMYK, then use In. Design to do the conversion when you make your PDF.(Some of you are saying, âBut I donât make a PDF, I send my native In. Design files to the printer.â Well, um, thatâs nice. We find sending PDF files to be far more reliable, assuming the file is created correctly. If you arenât sure how to make a great PDF file, see the links to our video courses and books at the end of this article.)Of course, your printer may request that you send an In. Design package with the PDF so that any necessary changes can be made more easily. Printers often have to modify otherwise perfect files to accommodate the final printing process. But if the file and the PDF is made correctly, they shouldnât need to touch your original files. How to Convert to CMYK When Exporting a PDFWhen your printer tells you they do prefer CMYK images, hereâs how to export your PDF files from In. Design: Choose File > Export. Choose PDF (Print) from the Format pop- up menu. Choose a PDF Preset (such as PDF/X- 1a if you want to flatten all your transparency, or PDF/X- 4 if you want to maintain your transparency). Set up all the other options in the Export PDF dialog box (compression, marks and bleeds, etc.)Finally (hereâs the important part), in the Output pane of the Export PDF dialog box, choose Convert to Destination (Preserve Numbers) from the Color Conversion pop- up menu. Do not choose âConvert to Destinationâ (without the âpreserve numbersâ) part, unless you really seriously know what youâre doing. Preserve Numbers means âif I have a CMYK image or CMYK colors in my file, then leave those alone.â You want that. Then, in the Destination pop- up menu, choose which CMYK you are targeting. Again, in the best case scenario, your printer will give you a color âprofileâ you should choose. But if they insist on CMYK, and for some reason canât provide a custom profile, ask if theyâre running the job on a web press or on a sheetfed press; then you can at least use canned profiles. For example, for uncoated stock on a sheetfed press, you might want to use Uncoated FOGRA2. Click Export. The PDF you get will be all CMYK and your printer will be happy. When It Makes Sense To Convert to CMYK Before Placing an Image. There are a few times when we convert images to CMYK in Photoshop before saving and placing into In. Design: First, if an image includes a color that must show up with a specific CMYK value. For example, letâs say you have an image of a banner with a giant corporate logo on it, and that logo has to be a particular CMYK value. Or if you have an image that contains an area of solid magenta that really is supposed to be solid, 1. Second, there are some image retouching situations where you really need to adjust just one plate. The classic example is when you have an image of a modelâs face and you want to adjust just the black plate. In those cases, we would convert to CMYK in Photoshop and then adjust the color on individual channels/plates to match the required color.
