HP Latex Issues – overheating the backing papers on vinyls.
Have had a HP latex for about 4 months and am getting issues with it almost over heating the backing paper on vinyls.
the paper becomes textured and this is also effecting the glue and making application difficult.
spoken to supplier of machine and despite trying with suggested material, on suggested profile and suggested RIP its still doing the same! banging head against brick wall.
Anyone else getting this issue!? -

What vinyls are you using?
Have you tried gradually reducing the drying and curing temperatures to see if this helps?
Did you try different vinyls? Some work better than others.Regards,

Hi James
Sounds like the heat setting is way too high – with Latex L25 and L26 models you should be able to cure/dry at no more than 110 degrees.
I have seen machines set as high as 130 degrees so they can print faster but this can cause the liner to blister …. Its actually cooking the PE coating on the liner. When we have suggested they drop temp down to 110 degrees and print at 10pass this generally cures any issues.
Best thing is to try dropping temp gradually as George has suggested, however if you drop temp too low you will have to increase pass rate (therefore slowing the print speed) to cure your print.
