How to design and transmit printed files for perfect bound or sewn book brochures and books with soft cover?

Whether your are looking for printing your perfect bound catalogues and magazines or your books, novels, art books, recipe book or travel books, please check this 6 important points corresponding to the 6 checkpoints related to the online printers before transmitting your proof.

Once receive your order, our teams will check your print files to make sure they match your configuration and can be processed without delays or errors.

NOTE: We are not required to proofread your documents and alert you to spelling errors.


Product dimensions (excluding bleed and cut lines) of your .pdf must match the size of the configured product.

Have a quiet area: no logo, text or visually important elements unless 1 cm all edges of the document.


When creating your visuals it is imperative before even starting to switch your creation software to CMYK Mode. Use the correct colorimetric mode in your models from the start by checking that the color profile selected during creation is CMYK (Cyan Magenta Yellow Black) and not RGB (Red Green Blue).


For a high-resolution printing of your quadri colour images, it must be transformed into CMYK, before being recorded. You have to check the 3 parameters to ensure that yours pictures are of sufficient quality for a high resolution print : definition, size and resolution.

A high resolution is considered to range from 250 to 300 DPI. You can go down to 200 DPI for a gray level picture. However, anything below this value will not be suitable for high quality printing.


Files must be transmitted in vectorized and flattened PDF format. If your file font is not “vectorized”, your text will be replaced on our computers by a proxy font. And your creation is not respected…


Your file must be configured with the corresponding crop marks in the ordered format (scale files will not be accepted). Crop marks show where your document wille be trimmed.

In addition, your file must always contain a lost background of at least 5mm bleed per side. Ink that prints beyond the trim edge of the page to ensure it extends to the edge of the page after trimming.

Bleed and crop marks are configurable when exporting your files (Illustrator and Indesign).

During the export of your file from your creation software (InDesign, Illustrator, Photoshop, Gimp, etc...) we recommend that you use the "Optimal quality" option to create Adobe PDF documents for high quality prints and proofs. It must conform to PDF-X 4.

For your print on coated paper (modern coated, graphic cardboard, premium coated, recycled coated, chrome coated, creativ paper coated) the output colorimetric profile to be used is the «ISOcoated v2_300.icc».

For your print on uncoated paper (White uncoated, bulk uncoated, color uncoated, digital uncoated, digital recycled uncoated, premium uncoated, recycled uncoated, creativ paper uncoated), the output colorimetric profile to be used is the «ISOuncoated.icc».

If you have not done so, we will change the intent of rendering your file in the production stream.
