What are we checking? The cover and the inner block can be in the same PDF. Therefore, it is important to correctly indicate which page the block starts from, and only then choose the print color and paper. The full route is collected in configurator instructions.
1. Specify the beginning of the block
If the first page of the PDF is used as the front cover, the inner block usually starts on the second page. If the document immediately begins with a title or text, choose the first. For a complex structure, check the actual sequence of pages in the PDF or leave the option to check with the Printto team and add a comment.

2. Choose a print color
| Mode | Suitable for | What to check |
|---|---|---|
| Black and white | Text, tables, linear diagrams | Colored elements will be converted to shades of gray |
| Colored | Illustrations, textbooks, diagrams | Thin light details and saturated fillings |
| Photo quality | Photo albums and rich graphics | Resolution and color profile |

3. Select the paper
White 80 g/m² universal for text books. White 100 or 120 g/m² denser and less translucent. Creamy has a warm shade and is comfortable for long reading. Smooth white better for images and smooth color fills.

4. Adjust the endpaper
The endpaper connects the book block to the hard cover. If it is to be in color or contain images, prepare separate content and leave a clear comment to the layout specialist: what to print on the front and back endpapers.

5. Check the result
- The starting page of the block is specified correctly.
- Color pages did not fall into black and white mode by accident.
- The paper corresponds to the number of illustrations and the nature of the reading.
- For the endpaper, there is a ready-made layout or a clear comment.
- After the changes, the thickness of the block and the availability of fasteners were checked.
