Here is my first try at a halftone, 305 mesh Udc-hv emulsion 6 bulb florescent exposure unit 8. 5 minutes let me know your thoughts and suggestions thanks
-
That looks pretty nice sweetts
-
Thanks, it was my first go with halftones, well the second the fist washed out on a 230 mesh
-
Thats a pretty big penny, lol. Nice job.
A trick I used quite often when printing designs like this was to use either true four color process black or a mixture of 50/50 4-clr process black and regular plasticol black inks.
Depending on the amount of large solid areas the 4-clr process black may not give the opacity needed yet in most cases works real well with a couple bonuses such as better dot control,minimal hand to the print and if you need to double print it usually isn't going to kill the halftones.
The 50/50 mixture helps with the opacity needed on certain colors. I used this mixture almost exclusively on all my prints unless I could get away with 4-clr process black.

Great trick, hopefully I will be doing more work like this and this is the first time with halftones so I am open to all and any help in getting this right. Thanks for looking at it

were your nerves up a little when you were washing it out? I had a couple jobs to wash out the other day, the one with all the detail and halftones came out beautiful the simple spot color spattered all over the back of my booth.

Yes I was freaking out, I also just started washing them out with the power washer so I was on edge boy. I didnt think it would come out, I use a florescent exposure unit with a weighted down piece of foam rubber, no vacuum blanket and I had a long burn time. Its very exciting to me to do something other then spot colors.

looks good!
what were the lpi and the angle?

that will help.
You could also set it up on two screens. Leave the solid stuff on one and the halftones with the sold stuff on another. This way solid areas will get two hits of ink and the halftones only one.

Great tip! I have ended up doing that before and it takes all of the anxiety way in regards to using multiple print strokes and loosing the half tones.
With that being said I wonder if this image was printed on one of those new Hi Density T's would it make a difference? I haven't used them yet but am super curious as to the validity of the ad that I saw with the dogs chasing the guy with the bacon on his shirt!!
Any one used the Hi Density T's yet? Would they work for this application?

I printed it on all my let overs I think the picture was on a port and co 6.1 the angle was 22.5 the lpi I am not sure where it was at

Good job sweetts, but I do want to clear up what I feel is a misnomer in terms here.
I have always been taught that spot colors are merely colors out of the bucket, as opposed to process and other colors "mixed" on the print itself. In other words solid, or halftoned, this is still a spot color job, albeit, using halftone dots.
Okay artists, rake me over the coals! lol!
-
Thanks I was thinking geez its still spot color isnt it , but didnt want to ask, glad you added that. I am still wet behind the ears lol :D

Great Job! I remember my first halftone job. I was scared sh!tless. The screen exposed and rinsed out nice. Then when I printed it.............it turned out really awesome. The customer was pleased.
-
Pierre looked at for me and made some suggestions, I will play with it some more to dial it in and repost a better print thanks for all the help

That's looking good. Which emulsion did you use, diazo, dual cure or Photopolymer?
-
Udc hv diazo I tried the green stuff you gave me but it kept blowing out, I am going to play with it more maybe a longer burn will help
