I've been trying to figure out how many times I need to pass over my screen to get enough ink down. I have heard different things.
Does anyone have suggestions for this aspect of the printing?

Re: How many passes needed to get good coverage?
Thu, May 3, 2007 - 3:01 PMAs many as it takes..
sorry..
I was taught as few as possible..but then the way I screen often there won't be enough ink coverage on certain parts of the screen etc...so I actually make several good strong passes. I prefer the image to be heavily inked rather than not inked enough.
I also have gotten to gauge areas where I don't think the ink has gone all the way through and I will spot fix those areas by running a spoon with a little ink over those parts. -

Thu, May 3, 2007 - 5:16 PMI thought that doing lots of passes might be bad technique but I am always afraid to not get enough ink down.
I know that by doing a lot you can distort your image. I would rather get a solid print though.
Thanks for the help, I'll probably be back for more ;D

heavy flood first...
maybe do the heavy flood on a test shirt to make sure all areas are damp with ink and then just add ink to you run as needed... -

Re: How many passes needed to get good coverage?
Fri, May 4, 2007 - 11:45 PMI've done a single pass before and got really bad coverage.
Maybe this has to do with my mesh or something of that nature. I am currently using multi-filament.
Could it be related to that?
I will have to experiment sometime soon when I can. -

Sun, May 6, 2007 - 1:49 AMkeep in mind too that different types of fabrics have different absorption abilities, with plastics (made from oil/esters, such as polyester, nylon, etc) being the least absorbent, then comes your proteins(silk, wool, mohair- animal fibers), and lastly, most absorbent are the plant fibers (hemp, cotton, linen).

Re: How many passes needed to get good coverage?
Tue, May 8, 2007 - 11:35 AMOf course the simple answer is, "How ever many passes it takes." However, the better answer is only one if you do everything right. But, aha, there is the key in getting everything right!
The simple truth is that your wet ink deposit is always equal to your stencil thickness, therefore in order to increase your ink deposit you need to increase your stencil thickness. Since the mesh accounts for 90-percent of the total stencil thickness, it is always advisable to choose the correct mesh thickness before attempting to make multiple passes.
