[IFGL]

I usually coat the next day.

John Robo - this is the product I use http://www.rustoleum.com/CBGProduct.asp?pid=100

not sure if I would want a high gloss finish on a canvas - one might as well then have diasec prints done

Not wanting to sound discourteous or anything, but what does all that have to do with sealing a printed canvas? If I'd received that in an email it would be bouncing so high by now it would probably stand a chance of meeting Mr Baumgartner!!

Hi guys

Purchase 2.5Ltrs of Glamour Matte Varnish and a foam roller. 24 hours ago we printed a couple of canvasses and applied the varnish to one. Before finishing the print started to 'crack' quite alarmingly!

We're obviously doing something wrong!

Any ideas?

Cheers

John

Here's a picture clearly illustrating the cracking.

I'm using Epson Ultrachrome inks & a cotton canvas with a polyester coating - I suspect this is where the problem lies! Polyester Inkjet Canvas (Satin). 250GSM, bright white cotton.

Looks like you have a non inkjet receptive surface or water resistant canvas.... you say polyester 250 which may be the problem..... Is it a branded canvas? is it an inkjet canvas?

[datasafe]

Thanks for the replies - very interesting.

Firstly the description of the canvas from the box is: Polyester Inkjet Canvas (Satin). 250GSM, bright white cotton. I believe I purchased this from Picture Master but not 100% sure.

The canvas pictured is the 1st we tried to coat with Glamour varnish and was roller applied. Yes, it could be the case that we didn't use enough varnish but I guess experimenting is the only way to find out. Does seem rather tetchy!

Cheers

Ah ha... Satin.... you don't normally have to coat the Satin or the Gloss stuff so maybe thats the problem.

One should wait 24 hours in my view.

[datasafe]

Thanks for the reply.

24hrs had been allowed for the print to dry before applying the Glamour varnish.

I have never used a giclee varnish with a nylon canvas, then again I have never used a nylon canvas. try Kevin art and canvas on ebay nice quality cotton canvas 360gsm very good prices. I used hanamhule canvas before I found this stuff, yes the hanamhule is better but there isn't much in it and for a quarter of the price .

Thanks for all the suggestions and help. This forum is really my only source of knowledge just now! As with many of the things we do, the learning curve is quite steep, especially at the beginning.

This is the route that led us to canvas printing:

1. We started out printing mugs using the dye-sublimation process. We took the wrong route at first and ended up wasting a bit of money.
2. Then along came t-shirt printing - again, using the dye-sub process. White shirts only.
3. CAD-CUT vinyl for garment decoration.
4. Embroidery - the biggest learning curve to date! We now have a 3 head machine.
5. Label printing with variable data i.e. incrementing serial numbers & barcodes using a Gerber Edge FX. Big learning curve but best income producer by far.
6. Direct to Garment Printing (DTG). Biggest investment, big learning curve but busy.
7. Recently we purchased an Epson 9800 so we could print some canvasses & family history charts.
8. And finally our latest addition - a Roland BN-20 solvent CMYK & metallic printer.

All this and I'm just about to turn 60 and my brain's hurting

Yes, we've trashed a bit of canvas and wasted a bit of ink but that's just to be expected I guess. We discover as we go and learn along the way

Yesterday Angie noticed a small mark on one of the canvasses we'd printed a few days earlier. She wet her finger and tried to rub it away, just using light pressure! It went away alright, as did the ink too So that brings another question - should that have happened? I guess the inks (Epson UltraChrome K3) are water based and therefore the answer I expect will be 'YES'?

Thanks

John

epson ultrachrome inks are waterproof when dry.

you have problems somewhere, your ink does not seem to be taking to the canvas you using.

[stcstc]

epson ultrachrome inks are waterproof when dry.

what gave you that idea

they are aqueous inks, even when dry, drop some water on them and they are toast

[IFGL]

waterproof is the wrong word, but if you put your print in a bucket of water it will not come off the paper or canvas or even so much as run.

It's best to practice the technique but once you had it its faster and generally better all round. I must admit we always varnish after stretching rather than before, mainly because you arne't moving the layer of varnish around during the process.
