Your screen uses three colors of light to define all other colors, this is the RGB (Red Green Blue) color model. However, printers do not work with light, but with ink or toner, and use the CMYK (Cyan, Magenta, Yellow, Key/black) color model.
Many images that come from the internet are made using RGB, and therefore do not match the requirements of the printer. If you upload an RGB file, there is a chance that the colors of the printed result will look less vivid than those on your screen. Additionally, very bright and intense colors that can be made with RGB cannot be achieved with CMYK.
To minimize the color differences between your file and our prints, it is important that the file uses CMYK colors. When your document is made using CMYK, the colors are most accurate. However, the colors you see on your screen are not a guarantee for the color that is printed. At Print&Bind we calibrate our printers every day, so the colors are transferred from screen to paper as well as possible.
Transfer to CMYK
If your file has already been made, you can choose to convert RGB colors to CMYK colors. You do this by exporting your file to PDF/X-1a:2001 with the profile 'Fogra39L' (if this is unavailable then choose Coated Fogra39. This profile allows for the best possible transfer from RGB to CMYK. If you have not made your file yet, you can choose to use the CMYK profile before you start designing.
It is not necessary to deliver a file with bleed and crop marks, but for a borderless file with a critical design, we do recommend it. Deliver the document with at least 3 mm bleed. For more information on how to add bleed to your documents with InDesign or Illustrator, you can check our useful tips. We advise against adding crop marks without bleed. When you upload a file without bleed, we will increase the size of the document slightly to create our own 'bleed' before printing.
It is possible that your file contains images or objects that are partially transparent, we call these transparencies. These transparencies are generally not visible in your document, but printers are unable to process these.

If you have designed your own font or used a font that is not a standard font, it is possible that when we receive the document this font has changed to one that you did not choose. You can't check this at home, and we can't know that this has happened. Therefore always include the font with your PDF. On our page with useful tips we have explanations on how to this for Word, Word on a mac, InDesign, and Illustrator.
Do you want to print a poster? Then consider saving your text as outlines. In Illustrator or in InDesign, you can do this by going to the menu and choosing 'Text' > 'Create outlines'. Make sure to save this file under a different name, as the text can't be changed anymore after creating outlines.
The attractiveness of a book depends heavily on the cover. When you choose the adhesive binding method, you can either upload loose pages for the cover or a spread document. With the first option, the spine will remain white, while with the latter you can include a design for on the spine.

Black in your document is not always the same black as our printers will print. Standard black in the CMYK color palette has the values C0 M0 Y0 K100, but the printers will generally print this as dark grey. To make a larger area black, the values C70 M50 Y30 K100 for designer black are more suitable. For lines or text, we do recommend using the standard black.
If you want to print a magazine or brochure, it is important that the number of pages is a multiple of four. That way it can be printed two-sided without any white pages in your document. If the number of pages in your file can not be divided by four, we will add white pages to the document, which you'll be able to see in the preview. Do not upload any spreads, just loose pages. Our system automatically puts the pages in the right order. For borderless magazines, we also increase the size slightly so we can cut it to the right size without any white borders appearing. If you do not want the size increased, then upload a file with crop marks and bleed.
Be careful with designs that fill two successive pages. There is a big chance that due to the shifting of paper, the design will not connect precisely. This also goes for documents that need to be folded.
Our system orders the pages of your document automatically. When you upload spreads, this order will longer be right. Are you unsure whether the loose pages you upload will be printed in the right order? In the order form, you can find a preview that shows you exactly how the end result will look!
We understand that many people like to design a framework around their documents. However, this is often not a very good choice for documents that need to be printed. With frames, there is a high chance that the edges do not become fully proportional and that the prints will look sloppy.
Important: There is no standard option in the order form for adding a glossy coating layer only to certain objects, so make sure to add a comment to your order saying you have uploaded a file with a coating layer for certain objects. This option is not available for books. To submit suitable files some knowledge on Adobe is required.
Here we provide a step-by-step explanation on how to design a coating layer for certain objects in Adobe Illustrator or InDesign.
Below we provide a step-by-step plan for setting up contour cutting lines in Adobe Illustrator or InDesign. With these cutting lines you can decide the shape in which we will cut your prints!
