Repeater halftone problem on rasters
-
@b77 Thanks!!!! I am going to try that and get back to you. This is exciting!
-
@VectorStyler Can a pseudo-separation be done using the color adjustment effects, so that each of four duplicates of a color image can have the cyan, the magenta, the yellow and the black separation, and Boldline doesn't need to export separation PDFs for this?
I tried a bit with the available effects but couldn't do it. Maybe I didn't try enough?
-
@b77 Maybe with the Curves color effect. Create four copies of an image and clump down all but one color channel curve on each.

Is there a way to get multiple color results from an imported raster image?
Just had a quick mess around by separating in Affinity, importing into VS and assigning repeater dots --- works great - obviously needs tweaking but opens up a few doors for creating duotones for T-shirts
-
@VectorStyler Nope, tried that. It applies cyan, magenta and yellow where's only black or grey.
Probably because the effect is RGB based (the image was changed to CMYK color mode).OK, I'll post a solution here if I find an effect that does this.

Wow just watched the video - giving me ideas how to do this in VS --- thanks
i though it would give us a few ideas
and maybe VectorStyler too

etched style halftones
There is a larger repeater task planned just after 1.2, so not very soon but soon.

@Boldline Export separations with Print to File and open the generated PDFs back in VS, change the black shapes to the correct color for the first three files (C, M, Y) or for the Pantones, and run Repeater on them.
@b77 Ok I'm finally trying this but I'm a complete newbie when it comes to most printing setups. I have it set to "print to file" and "separate", but am I supposed to be running it with all 4 CMYK?
Are there other settings I should be adjusting? Thanks for your help!
-
@Boldline That's it — hit OK and you should get one PDFs for each process color (C, M, Y, K).
-
@b77 ok - for this end result I really only want two colors, gray and white. It's going to go on a black shirt. Right now I have four pdfs that all look almost identical
-
@Boldline Then the white should be a spot color (a Pantone maybe) and make sure the grey object is made only of blacK ink — no mixing of cyan, magenta and yellow.
-
@b77 Can you give me a little more direction on how to go about adding a white in there and gray? Or point me to a place where I can learn how to do this? I'm not following what I need to do next - thanks
Am I supposed to be converting it to vector in Repeater first in this case?
-
@Boldline Oh, I thought you were dealing with vector objects, not bitmaps.
If it's monochrome, why do you need separations?
-
There are some small changes to repeaters. Editing the Intensity of the Object Content scaling mode allows now the selection of a color mode and color channel to be used as the intensity source.
-
@Boldline In any case, you can change the color mode of the bitmap to Grayscale from Effects > Adjust Colors > Color Mode.

Sorry for the confusion. In this case it's a raster image that I wanted to convert to a white screen and a gray screen with halftones. The white would not be halftoned. I wanted to see if this was possible in VS
Based on your thinking, How else would I did the separations?
-
@Boldline You can try vectorizing it and selecting only the white resulting objects that make the sprayed area (Select > Select by > Fill…), group them and give it a Pantone Translucent White, then convert a copy of the bitmap itself to Grayscale and use that for Repeater.
Other than that, since VS doesn't do bitmap masking, this would require an image editor like Photoshop or PhotoPaint which can do the needed masking and conversion to duotone (made of two Pantones).

I'm not sure if this is exactly what you want to achieve Boldline but heres a Vid-grab of how I'd tackle this, now I've got my head around repeater: https://drive.google.com/file/d/1cWbX3VjoKbr5FrhFsbnHSv4Bi_R01Dwv/view?usp=sharing
Excuse the poor video quality Vimeo won't let me upload now unless I start a PLAN (hate that word) so it's back to google drive
I have come across a few problems (maybe bugs) with the ruler guides not respecting Top-down coordinates and also the gradient mask tool flitting to the wrong place

Further to the above - thought I'd have a quick go with the ref image in the post and it all seems straight froward, although VS tracing is not as good as ImageVectorizer (which I would normally use) Really great that we can now access the symbol which is repeated in Raster work without having to create a symbol from scratch
