Submission for the expert

Your screen uses three colors of light to define all other colors: the RGB color composition (Red Green Blue). However, printers do not work with light, but with ink or toner and use the CMYK composition (Cyan, Magenta, Yellow, Black).

Many of the web-based images are formatted in RGB and thus do not meet the printer's requirements. The risk of submitting a RGB file, is that images are less 'color popping' than when you see them on your computerscreen. Also, RGB colors can be very clear and bright which is unfortunately not the case for CMYK colors.

In order to minimize the differences in color between your file and the actual prints, it therefore is important that your file is formatted in CMYK colors. If you design your document in CMYK, the colors will be most accurate with the colors on your screen. Do make sure that the colors you see on your screen are not a guarantee of the colors that will eventually be printed on paper by us. At, all printers are calibrated every single day, so that the colors are transferred from screen to paper as well as possible.

Convert to CMYK
Adobe users can convert files to CMYK: If your file has already been created, choose to convert the RGB colors to CMYK colors. To do this, export your file to PDF / X-1a: 2001 with the 'Fogra 37' profile. This profile ensures the best possible transfer of RGB to CMYK. If your file has not yet been created, choose the CYMK profile before you start designing.

It is not necessary to apply bleed or cropmarks to your document, but we do recommend this when you are submitting a document that is bordeless. The best thing to do, is to submit a document with a bleed of at least 3 mm with cropmarks. Read more about how to set up bleed in InDesign or Illustrator at our page with useful tips. Placing cropmarks without bleed is not recommended. If you want a borderless print but are not able to place bleed, we will enlarge the document a fraction to get some bleed. 

It's possible that your document contains images or objects that are partially transparent, which we call transparencies. These transparencies are usually not visible in your file, but can not be handled correctly by the printer. This looks as follows:

Faulty flattening

Good flattening

Therefore it is important that you remove any transparencies by flattening your files. Here's how to do this: In Illustrator you can flatten transparancies directly by using the "Smoothness transparency" option under "Object". In InDesign, do this as follows: Create a new profile under the 'Edit' tab. Choose what kind of resolution you want (high resolution), click on "new" and name your file. Then set the 'Grid / vector balance' from 100% to 75%. Then check the bottom box "Compressing Complex Regions". The other options are fine, so now you can confirm the settings by clicking OK. Then export your design to PDF and choose from the PDF menu at the top of the PDF / X-1a: 2001 preset. Choose from the "Advanced" menu on the left side "Transparency smoothing" for the newly created 'smoother' . 

If you have designed a font yourself or the font you used is not a default font, then we might print a different font than the one you chose. Unfortunately, you can not check at home if this will be the case. Therefore, make sure to always add the font to your PDF. You can choose the "Optimize for Publish and Print" option while saving your Word file, and then check "Complies with ISO 19005-1 (PDF/A)." Read more about embedding fonts in Adobe programs like InDesign and Illustrator on our page with useful tips.

If you save your work from an Adobe program, choose the option 'PDF/X-1a;2001'. This way, the font will automatically be attached when this setting is chosen. When ordering a poster, consider saving your text as contours. This can be done in Illustrator or in InDesign by selecting "Text" in the menu and then "Creating contours". Save this file under a different name, as the text can not be modified after making contours.

The attractiveness of a book depends heavily on the design of the cover since it's the first thing you see. When you decide to choose for a yarn-free binding method, you can submit loose pages to print the cover. With this option, the bookback remains unprinted and will therefore be white. If you do not want een white bookback but want de cover to be fully printed, you can also submit a spread document. This spread document of the outside of your cover will contain the frontcover (right), spine (middle), and backcover (left). If you also want the cover to be printed on the inside, that's possible. In this case, the inside of the frontcover should be placed on the left side. The inside of the backcover should be placed on the right side so when you flip the cover around, everything is in the right order. The inside of the spine will of course stay blank.


The width of the spread must be twice the width of the page + width of the bookspine. The width of the print is shown in the delivery conditions when uploading your file. The thickness is calculated by multiplying the number of pages and the thickness of the paper and can be found under delivery conditions under Size - Cover. There you can also find all the information you need to place your order. 

Is it not possible for you to make the cover or do you not want to spend to much time designing the cover? We have created templates of covers in A4 and A5 format. These templates are available for a bookspine of 5 to 15 mm. The covers can be downloaded in Word, Pages and InDesign format. You will reach the templates via this link.

The color black in your document is not always the same black color our printers print. Default black in the CMYK color palette has the values: C0 M0 Y0 K100.  However, this color often shows a dark gray color on the actual prints. In order to get a large area in a deep black color, it is important that other values are given to the kind of black you use.The C70 M50 Y30 K100 values for black are more suitable for filling in large areas. For lines or text, we recommend you use standard black. 

When ordering a magazine or brochure it is always important that the total number of pages is a multiple of 4, so it can be printed double-sided and there are no white pages in your brochure. In case the number of pages of your uploaded file is not divisible by 4, we will complete the file with white pages as shown in the preview. Please, do not submit any spreads, but loose pages. Our system automatically puts the pages in the correct order. Also in case of magazines, if a file is borderless, we will enlarge the design a fraction and cut it nicely to the desired size. If you do not want your document to be scaled by us, deliver the document with bleed and cropmarks. 

Be careful with designs that run over two consecutive pages. It is very likely that your design will not completely match in the middle of the two pages. The best thing to do is to avoid the use of this type of design as much as possible, or to accept that a small shift can appear.

Our system automatically puts the pages of your file in the correct order. When you submit your file in spreads, the sequence of your file will no longer be correct and errors may occur this way. Are you not completely sure if the page order of your file will be OK when submitting seperate pages? The preview in the order form will show you exactly what the final result will look like.

We understand that many people like to design a framework around their document. 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. Here we explain why and what you can do about it:

Minimalize the shifting of your design
Orders in sizes different from our standard sizes or ordered as "borderless printing" are always printed on larger paper with us and then cut back to the correct format. We also pay a lot of attention to producing and cutting the order. Yet it is not possible for us to cut precisely to 0.4 millimeters and it becomes difficult, especially with very large numbers, to always keep the frames the same size. This is because our paper already has a minimal deviation in size. We can't do anything about this, but we try to pay attention to it as much as possible. This means that there is also a slight shift on the paper that is not visible. However, there may also be a minimal deviation when cutting, together with the minimal deviation when printing, the deviation becomes slightly larger and it may (unfortunately) start to stand out.

What can you do about this?
If our system detects that there is a frame around the document, it is because the border is too thin. This means that a difference can arise and that the edge will not remain the same after cutting. Of course we try to avoid this on all levels as much as possible and to turn it into a beautiful end product! But to make it as beautiful as possible, we recommend not supplying frames smaller than 5 millimeters. Because the narrower the frame, the faster it stands out if something shifts. The submission of a design with frames always remains at your own risk.

The submission of a design with frames always remains at your own risk.

Note: The order option for coating specific objects is not available by default, so make sure to add a comment with your order that you have submitted a file with coating layer for specific objects. The submitting of the files requires some knowledge of Adobe.

Below you will find a brief step-by-step plan on how to create a special layer in Adobe Illustrator or InDesign, so that only certain objects in your file get a glossy coating layer:

1. Select New Swatch.

2. At Swatch name, enter ‘Clear’ (note that the first letter is capitalized!).

3. At Color Type you choose Spot Color.

4. Choose a striking color, such as Cyan, and move it fully to the right (100%).


5. Mask the objects or areas (for example with the Pen or Curvature tool) that you want to give a glossy coating. Do this with the Clear color you just created. Make sure Overprint fill is checked at Attributes if you have selected the mask!

6. Save your file as PDF/X-4.

Note: The order option for cutting specific shapes out signs or stickers is not available by default, so make sure to add a comment with your order that you have submitted a file with cutting outlines for specific shapes. The submitting of the files requires some knowledge of Adobe.

Below you will find a brief step-by-step plan on how to create a contour cutting line in Adobe Illustrator or InDesign, so that your stickers or sign can be cut into any shape!

1. Open the file that you want to have cut on the contour lines.

2. Copy the shape that you want to cut out and then paste it onto the foreground. So there are now two layers of the same shape. Select the top layer.

3. Click on the arrow icons to invert the 'Fill' and the 'Stroke', so that you can adjust the color of the stroke of the object and the inside is not filled.


4. Double click on the 'Stroke' icon and you can adjust the color of the stroke of the object to, for example, black. Click 'OK'.


5. Click on 'Window' and then click on 'Swatches'.


6. Select 'New Swatch' at the bottom right.


7. At Swatch name, enter "Thru-cut" (note that the first letter is capitalized!).

8. At 'Color Type' you choose 'Spot Color'.

9. Choose a striking color, such as Cyan, and move it to the right (100%).

10. Next, select the line and double-click in the 'Swatches' screen on the newly created 'Swatch' named 'Thru-cut'. The shape then gets a contour line, as below.

11. After this, add 10 mm bleed to the shape, so that no white edges appear when cutting. Select the original shape and select 'Object' and 'Path', and click on 'Offset Path'. Then enter 10 mm under 'Offset' and click on 'OK'.


12. Finally, save the file as PDF/X-1a:2001.
