Ceramic Coasters and Laser Transfer paper printing problems

[johna1954]

Hi everyone, appreciate any help you can offer this newbie to sublimation printing.
I am using TitanX Laser transfer paper onto ceramic coasters. The heat press is a Galaxy model (new) I pressed with - baking sheet/coaster/baking sheet/silicone mat - for 180 secs at 190⁰ C.
I have tried to ensure that the paper is dry and coaster slightly warm (attempt to ensure no moisture).
I do not seem to be able to get a consistant print across the whole coaster as you can see from the picture.
I am ruling out the paper as the result in the rest of the coaster is ok and have tried different areas on the press (15" square platten) I am only doing one at a time as new to this and trying not to waste too many coasters!
I am veering towards uneven pressure or a problem with the coasters themselves but with my lack of experience with this type of printing am not sure and therefore would ask for your comments.
TIA

John

Hi John

This might not be want you want to hear and I will try and be as diplomatic as I can.

It might be that you do not get too many responses due to the supplier of the laser paper, that is purely speculation and you can search around and find out most reasons why this is the case so I will not elaborate.

Having said that, why are you using laser paper to print on coasters? Would it not be better to dye sub? It will be a better finish and a far superior product.

Hi socialgiraffe,
I am using laser paper as I already have a suitable high quality laser printer and this seemed the way to go without the expense of yet another printer, which probably is not compatible with the Linux operating system I use for all my work.
