For DIN A5 book printing (210 x 297 mm), 64 pages, the printing cost can vary based on several factors such as:

Quantity: The more books you print, the lower the cost per book will be.
Paper stock: Different paper stocks have different prices and weights, so the cost will vary based on the type of paper you choose.
Color options: Full color printing is more expensive than black and white printing. The cost will also depend on the number of colors used in the design.
Binding: Different binding methods have different costs, so the type of binding you choose will affect the overall printing cost.
Finishing options: Additional finishing options, such as laminating, die-cutting, or foiling, will add to the cost of printing.
Printing technology: The printing technology used can also affect the cost, with digital printing being generally more cost-effective for smaller quantities, and offset printing being more economical for larger runs.

Location: Printing costs can vary based on the location of the printer and the shipping cost of the finished books to your location.

Paper stock: The type of paper you choose can affect the cost. Heavier weight paper will generally cost more than lighter weight paper.

Processing: adhesive binding (soft cover)
To produce a PDF file with adhesive binding (soft cover) format, please follow these steps:

Set your document size to 8.5″ x 12″ in your design software.

Ensure that all pages are in continuous order, without any overlapping or spilling of content onto another page. This will help prevent optical offsetting during the printing process.

Save your file as a PDF, making sure to choose the “high quality print” or “press quality” option.
The final printed product will have a format of 21.0 cm x 29.7 cm, so be sure to check that all elements of your design are within these dimensions and are legible at the new size.

Once your PDF is ready, you can send it for printing, making sure to specify that you want an adhesive binding (soft cover) finish.

Note: It is always a good idea to proofread and double-check your file before sending it for printing to ensure that everything is correct.

Safety distance:
This text provides important guidelines for the design of a book cover. It specifies that texts and images that are critical to the design should be placed at least 5 millimeters away from the final format. This is to ensure that the final product is not cut off or distorted, due to any cutting tolerances in the production process.

Additionally, the note regarding the spine mentions that there is a tolerance of up to 10% in the production of the spine. This means that the width of the spine may vary by up to 10% in the final product. It is important to take this into consideration while designing the cover, to ensure that the design is not affected by any changes in the spine width.
