seeing similar problems on Korographics Abaco Beach
Hi All -
Just going to through my 2 cents in here. We have an HP Latex 360 and have seen the same issue on Korographics Abaco Beach. It is a result (in my opinion) that the material stretches/shrinks too much and does not lay flat on the printer platen, so the ink lay down is different in the highs and lows. After discussing this with our media vendor he said that most (not all) wall papers are made in the same fashion where a vinyl/pvc substrate is pulled out onto a large embossing table and then a big stamp comes down and uses heat/pressure to emboss the texture onto the material. The main problem is that the typical embossing plate is only 27" wide, so it is run down each side of the material (which is why you can see color shading from one side of the roll to the other), and this process actually stretches out the media in the center of the roll and results in uneven tension on the roll of media so it's very difficult to have the media rest flat on the platen (have you ever noticed how wavy this stuff is - wall covering)... Anyway our vendor has specified two materials that are very similar to Dreamscape/Korographics wall coverings that are embossed using a 54" wide plate that doesn't cause the problems a 27" embossing plate does.
You may find yourself asking why then the manufacturers wouldn't get a 54" plate for their medias and solve this problem? As I understand it, the problems we experience on solvent/latex printers are not issues when you have a UV belt driven hybrid flatbed printer (but not every printer can buy one of those for $250K or more) because the uv inks site on top of the media vs. biting into the media (like a solvent/latex ink would).
I'm testing the 54" wide embossed media for about 8 or 9 murals over the next month, you can find my results on my other post if you are interested, here is a link:

I hope this can help someone who is battling with all the headaches we have been!
Best of luck to everyone!
