Retouching Photos: Photoshop and Illustrator Q&A - Page 4

modillustr · 03-12-2007

Are your watercolors B&W or "sépia" ones? "halftone" means "demi-teinte"?

Make a 300 DPI scan of the illustration (B&W or color),save it as a JPG file or convert it as PSD file in photoshop.(very often one have to "clean" the scan and PSD file keeps the quality and info of color for each pixel).

Do you mean you want/have to do yourself offset printing screen film(you speak of frequency and size of dot," offset printing dot"?) ?
Usually, you give the file (JPG or PSD, sometimes EPS)to the printer (or the graphic designer) they convert your file from "three screen color"(RedGreenBlue)(the computer image file mode) in the four printing color(CyanMagentaYellowBlack), and then after make the offset printing film screen.
Hope it may help you...

That kind of effect is called vector, you can find at the youtube videos theaching how to do a vector, it takes a long time to do it ...

thanks for your response, modillustr
what i'm doing is using these 'halftone' images for screen-printing (or serigraphy)
gradients don't print well with this technique, so i have to change it to dots

you can see these dots in works by Roy Lichtenstein or any other comics artist

The same effect is done when you do hatching with pencil or pen

i had to do my own tests because I'm using a specific mesh size and I'm also printing on fabric
I think my tests are successful now

oh here is my new problem...

left: original photo
right: edited photo

usajrf.org

i used the Posterize function in Photoshop to achieve this effect
I'd like to separate those different layers (dark, medium, light greys)
Is there a way?
Or maybe there is another way I could use to create layers (for a multi-colour layered screen print)

About Avant garde question:
First... I tryed to read the signature , "foto e dipinti Nasvel?"and got no valable info on google with "nasvel+photo".

It could have been (perfect10 or mikelowrey point of vue) or not have been done with photoshop(traditionnal way, drawn on a layer over a photo print and then after digitally gathered/Allius 'one).I see no particular problem to do it with photoshop mixing the use of tools(effects), brushes and pencils on a layer.It just remind me the advertising agency "rough/sketches" made with felt pens on "transparent" paper(Schoellershammer's paper for example) of the 80's.No really interesting.

Thanks gius, with your answer, I understand better.
I searched the french word "tramer" on google and I got "halftone screen".
Therefore we are speaking of the same technique.
As I sayed I have never done myself "halftone screen" for a computer image.
I just have found some technical pages on google, but you certainly know them.

You can use the "select color range" or the magic wand tool with a high sensitivity to make a selection of each separate gray tone. Then hit copy, make a new layer, and paste. Repeat for each shade, and you'll have a layer for each.

I am having a problem with Photoshop CS 8.0

. Whenever I try to open up Adobe Photoshop CS it goes about its business and then stops at "Reading Text Global Resources... Done" and the title of the window says "Adobe Photoshop CS (Not Responding)".

if your a student you can get the student version for like 1/4 of the original price. its made of win!

gius · 31-03-2008

The student version doesn't lack in anything , does it ? For example, missing filters, functions, etc. as if it is just a demo version

I actually have Photoshop already--just considering getting a different program while I'm a student

lemeray · 31-03-2008

The student version is great. Your not really missing anything, definetly not a demo version thing...I got the whole Adobe package for $200

Mchunu · 31-03-2008

nope not a thing!! I just bought the CS3 Extended from Amazon for £140...a fraction of the £600 price tag for the "normal" version. Everything is the exact same and not a single thing missing!!
