Print data prep for packaging production

To produce a high quality final product, it is necessary to provide the print data according to the following rules:

Use the TrimBox to define the intended dimension of the finished page (the so-called “trimmed size”).
The objects stretching to the edge of the trimmed size need to extend beyond the trimming frame by at least 3 mm (bleed). Use the BleedBox to determine the size of the bleed.
Raster PDF images must be of sufficient resolution – 300 dpi for offset printing (200 dpi is the minimum).
Colors – for vector graphics and text, choose CMYK or spot colors (Pantone). The PDF/X-1a standard allows only CMYK and Pantone, the PDF/X-4 standard allows other color spaces. However, for a safe handover, we recommend that you stay with CMYK and Pantone.
If you use color management in your document, always use the PDF/X-1a and PDF/X-4 standards. Output intent – for example: ISO Coated v2 (FOGRA39) or PSO Coated v3 (FOGRA51). For documents without color management, use PDF version 1.3.
Fonts – all fonts must be embedded.
In the document, set the overprinting of inks exactly as they are going to be in the print. We automatically overprint objects that are in 100% black color.
Always put the drawing of a die-cutting form in a spot color into the data with graphics, preferably under the name die-cut.
In the case of other finishing treatments (such as UV varnish, hot-foil stamping, embossing, etc.), insert graphics in a spot color with an appropriate name.
