poly paper questions

[Adam McGuire]

Hi George,

By poly paper do you mean waterproof poster paper / hydrosol? If so, I have used it a bit recently, albeit 2 completely different brands because Robert Horne don’t seem to use the same supplier twice… The first I used was like glossy photo paper and the results from the Mimaki were absolutely brilliant. This lastest stuff feels cheaper and has a more matt finish. Not bad results but the material profiles needed to be changed so quite a bit has been wasted and a couple of jobs reprinted.

Hope we are talking about the same stuff! 🙂

As with Adam I have used various Hydrosols with good results but be careful with the drying as it takes a lot longer than vinyl. We tend to put a heater in front of it to assist the drying.

Gary Adam thanks for the replies I have no idea what hydrosol is? Is it the same stuff used for roller banners? The guy making the enquiry said its 1 to 2mm thick and is used for photo shoot back drops?

You can get it about 300gsm but it isn’t as think as that mate. I would give Robert Horne a call and get some samples.

1-2mm thick? Would that go through a solvent printer?

Hydrosol is a coated plastic material around about the thickness of banner, probably a little thinner and it has a smooth finish rather than banner style texture. It allows light through so I’ve been using it for light box posters amongst other things but it’s not transparent.

I forgot to mention earlier the drying time is long! Also be careful with the printer t see temperatures as it tends to ripple because there is no adhesive or liner. Turn down the tension on your take up roller if you’re using it as the solvent will weld it all together! Well not quite that bad but you know what I mean. We use a slow profile with the temps turned down to give it more drying time before the take up.

After all that it might not be the product yoh are after!
