screen printing

[Paul]

Well. It look like i need to buy few more screens

Try thinning your ink a little, if no good try a different squeegie and if still no joy go and get a 62T screen - give it a go. You might have a good screen supplier but I use Colenso for my screens (wood frames).

Cheers John

I use aluminium ones. Can you post some links to good supliers? What emulsion do you use and how long it takes to expose it? What price etc... i am realy looking forward to start ne hobby. Fantastic add on to sublimation.

Also we have members to members ofers so you ,ay want to post some discounts to dorum members.

Hi Paul, Colenso do metal frames too but there's bound to be a screen stretcher near you which would save the delivery charges - try yellow pages.

I use colenso for squeegies, screens and emulsion "Fotecoat 1072"
Sericol for all my inks - there are other suppliers but you do get what you pay for!
Litho Supplies for latex gloves, scalpel blades/knives and MEK - a fast drying blanket wash normally used in litho printing but brillaint for cleaning a stencil which will be used again or squeegies.

Exposure time will vary depending on the darkness of possie, thickness of emulsion and the distance between light source and glass. My screens take 4.5 minutes but I have used exposure units that can do it inbetween 1 and 3 minutes.

Cheers John

I use the square type G1 but haven't ordered any blades for ages as I kind of had large stocks from previous employment.

I suppose its what you get used to - when I first started in printing all you could get were square squeegee's so that what I use. Stuck in my ways old F&rt.

Basically its all trial and error and practice makes perfect.
