Most delays in printing arise not on the press but in the file. Missing bleed, an image in RGB or a font that is not embedded can set a project back by days. In the worst case, the job is printed incorrectly. Here are the most common mistakes and how to avoid them.
Trimming involves minimal tolerances. Without bleed, white edges can appear. Solution: extend backgrounds and edge-to-edge images 3 mm beyond the final format.
Important content right at the trim or fold line can be cut off. Solution: keep a safety margin from the edge and from crease and fold lines.
Screen colours (RGB) are converted for printing. Bright shades can look dull and distorted as a result. Solution: create data in CMYK with the right colour profile. More in our article CMYK and Pantone.
Images from the internet or heavily enlarged photos become pixelated in print. Solution: at least 300 dpi at actual print size.
Missing fonts are replaced with substitute fonts. The layout shifts. Solution: embed fonts in the PDF or convert them to outlines.
Small black text made up of all four inks becomes blurred with the slightest registration deviation. Solution: set text in pure black (100% K). For large black areas, on the other hand, a rich black with added colour is recommended.
Hairlines can break up or disappear in print, especially in reversed-out text or with finishes. Solution: use sufficient line weights. We will gladly advise you on minimum values.
A Pantone colour accidentally converted to CMYK, or several differently named versions of the same colour, lead to errors. Solution: name spot colours clearly as HKS or Pantone and use them consistently.
Solution: always work with the printer’s original template and check a folded mock-up. We provide templates for your style of box.
Hot foil, spot varnish or embossing need their own data. Solution: set up finishing areas as a separate layer or spot colour, in exact register with the design.
White objects set to overprint disappear in print. Solution: check overprint settings before exporting.
Unreadable barcodes are particularly annoying on packaging. Solution: respect the minimum size and use dark bars on a light background, ideally in pure black.
