Silkscreen Testing...Experiment #1

My first attempt at exposing my emulsion coated screens with a new design was a failure. The only success that came from it up to this point was the box to hold screens and the tweaks to the garage to completely make it into a dark room. With this first attempt there have come some hiccups.

When in class at LBCC I was using Speedball emulsion. With this emulsion I was able to expose a screen to light for 16 mins then rinse and let dry. When it was successful you could see through the washed away unexposed areas. With this emulsion little bit trickier. Of course I assumed (if you assume your an "ass") that the same light exposure time I used at school was the same for my experiment. WRONG!

The emulsion I am using is Ulano 925WR. I took a look at the tech sheet I noticed that there are 3 different methods of coating a screen, I use the "Method 1." Apply one coat of emulsion on the printing side, then dry the screen thoroughly. I did not apply emulsion on the squeegee side as the tech sheet specified.

My exposure time was way off. I'm am using one 250 watt bulb, but my exposure time was too much. One screen at 24 mins and the second at 20 mins. I was only supposed to expose it for 7.5 mins. My exposure distance was less than 20 inches. Will definitely keep distance in mind for the next test.

This is just the first of many tests that I will be doing and updating my blog about until I create my first print. Lots of different factors come into play but I am almost on my way. STAY DIRTY!

The final product and my 50th post.

This Sunday Robert G. and I finished the box that we set out to build back two weeks ago. Purchased two more stud pillars and three more half stud pillars. Reason for doing so was to really give the box some more support. All in all the box came out great. I am able to hold 10 19x22 inch screens and have some room to hold my paints, emulsion, scooper and many other things. Overall this box has cost me $50+ to build and it was done pretty quickly.

Starting this week I will be testing the box itself for any light leaks. Also I will give the door of the box a rubber sealing so that no light can leak from the front. As of now I have plans to test and make this box cherry. By the end of the month I should be printing shirts, totebags and more.

Lastly this is my 50th blog entry and it's been great. I've only been on since June of 2008 and it feels like yesterday I was talking about how my business and I are just starting out to now being able to print my own stuff and really take charge of what we are producing. I look forward to this next month and showing you what we can accomplish.

Making a silkscreen rack.

So this past sunday me and boy Robert G. began building a silkscreen rack so that I can coat the screen with emulsion and let them dry horizontally and in a dark area so they are not exposed to any kind of light. So when they are dry and ready to expose. Also is great storage for them.

Materials need to build a 4 foot high box with wheels (all purchased at Home Depot):


wood studs 4
half stud 8
3 1/2 inch wheels
a latch
silicone
2 8 foot plywood (as cheap as posssible)
6 - 10 nail bridge (picture below list)
lots of small nails (if you have a nail gun even better)
wood glue

"nail bridge"

On the fly with just talks we were able to sketch out what we wanted did some measurements came
up with this pretty good box. Unique to for us to work with. Storing screens and let them get ready for burning my silkscreens and getting ready to print.

Next week should be the finished product and we'll begin to silkscreening next month some stuff and we'll surprise you with what we are going to start with. STAY DIRTY!
