Can you see the halftone dots?

I can't see dots.  Looks good.






Question for you discharge expert guys/gals.   I was thinking about this today.  I have a customer (lets call him BUCK).  Buck request me to separate the discharge jobs (sim process of 4-8 colors usually, and ---he wants them all to have 100% SOLID coverage by the time it's all said and done but also does not want to use a discharge underbase. Only a top (highlight white) if white is needed. Meaning,
even tho it's all halftone, the fact that it's discharge indicated to him that he needs ALL shirt color to have a total of 100% coverage when laid over top each other so no shirt comes through.


So, a way to check this is, after you do your seps, you select each one, and combine them all onto a new channel and read your coverage.  Then you determine where you are not getting the most coverage and see what color can be beefed up. 


To me, How do you do that...when you have no base white...cuz it's all discharge colors?
I don't feel this is the right way. when you adjust to (fill in), just for the sake of filling in to cover shirt color, you are messing with the colors and look. It aint right.  Thoughts?

Dan.........I'm not a seps pro per se but I do assist in the separation process, especially for discharge. Your method described above usually will work. Take this simple example: This shirt used two screens each with a fade and no UB. I had the artist play with the fade a few times until we knew we were going capture some nice tertiary colors. When you overlay the two films the image is now black.
Not sure if that helps. BTW this print was stupid easy.

Looks good Tony... nope, can't see the dots.

What are the details?  LPI, mesh count blah blah blah.

I can understand that when dealing with a single color blending into another color to get a 3rd color etc.  But for sim process (of a photo) or picture of art, it seems far less accurate to do it that way. How can you match an image?  Too haphazard for me. I need solid confirmation that it will come out as accurate as possible.

Dan I don't have the seps anymore but perhaps this image will help. I do have a sim process photo "postcard" image from St Thomas that we did a few ys back and do still have the files. We'll print it sometime in the near future. That may enlighten you some.
This is a nine color sim process discharge. Can't seem to get a great photo of it.

That IS a great print. It's not illustrating what I'm thinking but it's a good example of how to handle that specific job.


I guess I'm coming from the idea of how to approach using a set of colors lets say 4 color process with no underbase... where all  (halftones) are used to blend or mix (to make specific color areas. How do you attempt to "match" a color if you need to fill in to get 100% coverage?


In your example above, it is sim process (in a more basic example). like where you have the beige flesh color, then either a highlight lighter beige or a very faint hit of white highlight...and then for the shadow, you have one other "specific color such as a brown for shading. Here, you are using 3 specific spot colors to create that body of flesh. The color choices are already set so it can't jump to another color tone buy saturating the flesh area with beige for example.


With many of my customers being on a 6-7 color press, some of my sim process seps require more "accurate blending" of each spot color to achieve other target colors. Similar to 4 color process.  For example, If I were to use discharge inks in primary colors of Red, Yellow and Blue + black + White highlight to achieve a full color print on dark shirts,  I need those colors to be more on target with a % of the colors.


Lets say, I use 15% of blue, 35% yellow and 10% red and 10% black + 10% white. That has to be (THAT) %.  I can't adjust curves and fill in on anyone color just to get 100% coverage. I can try, but it often never fills in 100% solid and it veers away from my more accurate color % choices. I'm just thinking that via discharge, critical color matching jobs are not that accurate...if you must fill in solid. So, in some scenarios of using discharge, I believe it's less accurate and therefore, if your art customer (demands) to be accurate, maybe discharge is not the best option.  Just think ing out loud.
