bigger print than a4

Postby martinmckenna » Sun Oct 19, 2008 10:19 am

ive found out that to make a print bigger than a4 , the best way to do it it to use tracing paper ,the eca will print onto tracing paper up to a0 . Am also being told this better than actate , as the toner sticks to it better .

ill will look into how much a4 and a3 tracing paper is . it also has to be of a certain type .

i am also assuming it will take longer than 23 mins to expose , ill have to do a test print ,

seems as if tracing paper is called vellum in the trade

heres an interesting article on exposure

http://www.smrsoftware.com/vellumexposure.php

it has a test sheet to use .



ive prepared a new screen with the new emulsion , it pretty thick stuff . but it does go on . ive applied the emulsion using the Squeegee rather than that thing we normally use .

ill do a test with acetate and the "vellum"
