Hi does anyone know this??? Im trying to create some very very fine halftone detail on a t shirt(so it looks almost photographic). How does the dpi relate to the lpi. If i give the printer artwork that is 600dpi or 300dpi will it make a difference?also if i want great detail in a screen (for example like fading a seamles blend)how am best producing the artwork( one colour bitmaps?)if so what setting dpi/lpi. etc thanks

Check out Jimiyos tutorial on halftones on you tube..

I think 600 is overkill and would just make a huge file to send, usually 300 is sufficient..

I always understood that the DPI of your image should be at least 2X the LPI of your screen.

Here is a great article discussing LPI vs DPI...

I saw that video. Problem, after the bitmap halftone is used the line art goes to hell. Unless It doesn't matter that much cuz of the mesh of the shirt.

sorry i dont undrstand what you mean can you rephrase for the newbie. thanks a lot

In the video,after the bitmap part, you look at the line of the wings or the skull. It now has hair...lol. He said the art was vector. So, now the how sharp are the lines(black shapes).

I'm new to this as well. I'm looking to make "Dots" but make sharp type.

I saw that pic of the shirt from the other thread. Can stuff be added to the ink to thin it out. Couple screens of different levels of thin kinda thing; just a thought tho.

You guys are over-thinking the halftone process.

Convert to grayscale - dont merge layers
convert to bitmap
select 300 res w/ halftone screen
pick the amount of "dots" you want by playing with different numbers and your golden

....must be, over thinking, coz I'm from a vinyl background and the edge like that would fun. I've got some test files I'm going to run Thanx

This stuff is pretty easy, the effect is all in the production.

The art was probably built first in vector, then brought into photoshop and "destroyed" by painting it out and adding distress layers.

Once you have it grunged up enough you just output as tiff files at a suitable lpi 45 or 50 maybe.. then the printer used a high mesh and probably printed with waterbased ink.

Probably a half hour of extra work in photoshop if you have a few ready made distress files lying around.
