Printing, Stickers, etc.

[Stevonez]

I printed promotional products for many years... using both the screen technique and pad... contents of the inkwell have a lot to do with how long a print will hold up... as in the ratio of ink... hardner... and the amount of thinner used...

most of the prints I'm familar with are no bigger than the inside of your palm... tee shirts and such I haven't any experience with...

with pad printing metal plates are used... an image is burned into the plate and then placed in an inkwell... a blade pulls ink over the plate then another sharper blade pulls the ink away... a pad then comes down and strikes the plate picking up ink ready to transfer to the product... this all happens in a few seconds... pad pressure determines how distorted the image outcome will be...

screen printing involves a cheesecloth type material with the image burned directly into the screen... ink is poured directly into the screen area and using what is called a squeegee the ink is applied directly to the product... depending on the amount of pressure used while applying determines the coverage or thickness of the ink prints...

both processes are much tougher to master than one might think... there is so much that goes into the preparation process that it is just to hard to explain without seeing it...

I saw a simplified, "home" version of this involving actual cheesecloth and glue to create the screen image, then using paint to print an image on a t-shirt. The process to put the image on the screen was tedious and took some time, though. How are they "burning" the screens, today? All computer based (laser?) or something like a robotic cutter?

the printing shop I worked at used these high powered lights to transfer an image from a film like material to the screen itself... then any unwanted "pinholes" were covered with a rubberized substance that blocked any unwanted ink from seeping through... the whole process is really interesting when you know what all goes into it... I haven't worked in the printing field for over 7 years now and I still find myself looking at different products to see if I can see any mistakes that might have been made during the process...

Just noticed you're from Tampa Kitsune... the shop I worked for was called AdvaLite... located in Largo of Pinellas county...

me again... I was looking around on the net after thinking about this conversation and came across this site it might give you a better understanding of the types of pad printing machines used and how they function...

Those are some sexy machines! Wow! I don't think I want to know what a decent pad printer runs!

For my own work, I found some online places that seem to have reasonable minimums as far as sticker orders go, so I may give them a shot if I can come up with a decent design. Meanwhile, I found out that you can do window cling-like printing with an inkjet, but it is absolutely miserable in quality and appearance. Blegh.

I think I'm going to have to sneak into the print shop at the university someday to see this for myself. They do a lot of screen work over there, I've been told, and I occassionally see old equipment being tossed. I have no intentions of trying to bring any of it back to life, but I couldn't believe they decided to junk a vacuum form machine rather than repair it!

yeah they can get quite pricey...

yeah I've thought about perhaps trying something simular but decided against it... the cost outweighs the benefits for me...

Sounds like a good plan with the interest you have in it... good luck with it...
