more registration stuff

I’m picking up from the last time I left off on my visiting card printing progress. It’s been quite a while! Apologies. A lot has happened since then. As in, in my experiments. hahaha.

a. 20 minutes of exposing wasn’t really working for me. Too much exposure means that my photo emulsion doesn’t come off when washed with water. So, i’ve come down to 15 minutes. i find this website helpful for screen printing tips:

b. i switched to johnson baby oil even though it is quite costly. i realized it is less greasy and dries faster and smells better (and leaves me with softer hands). LOL

1. That’s my screen with photo emulsion on. It’s supposed to be done in a relatively dark place but more importantly, you HAVE to dry it in a dark place. It takes sometime to dry. You need to have your stencil ready for exposure before you bring out your screen to the light box or whatever exposure unit or sunlight.

2. My light box: I’ve placed my stencil on top of the glass – facing the RIGHT way up. In screen printing, unlike other printing techniques such as etching and relief printing, you don’t reverse your image like you do on the plate or block, respectively.

3. sorry, i don’t have photos of exposing yet, coz i do it in the dark. but i’ll have some mock photos up soon. what happens is that i put the screen with photo emulsion, flat on the stencil. the important part here, is it make sure that all of the stencil is in contact with the screen. to ensure that, i use a sheet of glass and lay it on top of the screen. so it would be: the glass top of the light box, the stencil, the screen and then another piece of glass.

i turn on the light and expose the screen for 15 minutes. immediately after that, i take it to the tap and put water on both sides of the screen. i use a mug and bata. i have the bata filled with water and then when i wash the screen, i recollect the water in the bata itself. i try to save water, since we have so so so much of it available in kathmandu.

your drawing slowly reveals, and walla! you have ur screen ready (after it is dry).

4. so this is going back to the previous post on printing and registration. i have my tracing paper ready and i first print on it. i decided to go with blue ink.

5. i line up my paper (pre cut lokta paper made for visiting cards. can be bought in 100 pieces), with the print on the tracing paper and use masking tape to make my registration marks.

6 & 7. i lift the tracing paper and then print. and repeat the process until i’m done printing some 80 cards.

and then, i call it a day. i’m very excited to print the next set in red. hahahaha.
