Photopolymer plate impression/relief
I have a small Adana HS2 press and I am looking to purchase photopolymer plates.
I would like some expert opinions on how good a relief you can get with the regular adhesive backed photopolymer plates?
My supplier in the UK said that to get a relief I should get the steel backed photopolymer plates, but looking around on the internet it seems you can get a good relief without the steel backing?
I realise it depends on the paper I use too.
Thanks for your help!

I guess it comes down to what you mean by “good” relief. This somewhat depends upon thickness and backing and manufacturer/brand. And your press as well. If you are looking for a very deep impression, I doubt your press is capable.
Thinner plates will give you a slightly better resolution in most cases. Steel-backed plates provide a stronger relief structure, won’t warp imaging or stretch, etc. Thicker plates don’t actually provide more impression. Impression comes from above the printing surface not below.
Somewhat of a judgment call. Probably best to stick with a trusted local supplier.

Sorry for the silence!
I have been able to test out some steel backed photopolymer and flexo-plate plates on my Adana HS2.
I am not looking for a very deep impression but at least some.
I understand that I probably could not get an impression on the full 6x4” area but the samples I am using are only around 2.5x1.5”.
I have used normal writing paper, 90gsm cartridge paper, 300gsm recycled cotton paper, and 300gsm recycled card. I am using swiss style packing from Happy Dragons Press, and have also tried padding it out further, and making it harder.
When I bought my Adana, it needed a very good clean and I had to remove the impression screws and take everything apart. Now of course, to my dismay, I can’t seem to adjust the screws to get an even impression! I have read and re-read the manuals, researched on the internet, tried adjusting them on the diagonal etc, and will keep persevering, but any tips from anyone would be great!
