The artwork isn't screen printed... its digitally printed on a white background. You can tell this by looking at the shading. A digital print will make many pass overs and place small dots where colour is needed. Go to a shade out and the dots become less. The eye then blends these in so long as it is from a distance. Most machines don't print white.. they are CMYK and print OVER a flat white sheet.

You can clearly see this on the highlighted area and also how the print head passed horizontally over the white substrate.




So.. this then begs another question... is it printed direct to the timber...or... is it printed to a vinyl and then applied?

If to a vinyl, then it may be the vinyl substrate that is getting dented... if direct to timber, then it must be the timber.
The CC is quite thin and the dimples look to go beyond the depth of that.

Anyone with a Stern able to take a pic of the PF edge?... If you see a thin white line at the very top where the artwork is then you may well have yourself a digital print to vinyl that is applied as the artwork.
