Hello everyone.

I don't know why when i try to create a bitmap image with LINES or DOTS it works just with the texture below.

I use the method HALFTONE SCREEN, but if i select the shape as ROUND or LINE, nothing change and the result is always the texture below.

Someone know why ?

Thanks in advance !

And if you colorise the artwork in Photoshop anyway you could also use a Pattern Layer set to Blend Mode »Hard Mix«, which might provide better edibility.

When you convert to bitmap, what is the Output Resolution you are choosing? It should be rather higher than the Input Resolution:

Then, choose a low value for the Line Frequency:

When you convert back to Grayscale, I would recommend using 1 for the Size Ratio, and then using Image Size to resize the result, as this offers more control.

Hi matibuc4eva

Did you find a solution to your problem?

No matter what "shape" option I use under bitmap > halftone > shape (round, diamond, elipse etc etc) they all come out in a pixelated style (see pics).

My picture is 300dpi and I turned it into CMYK and then tried to BITMAP.

Your Output Resolution is less than four times your Screen Frequency, so you anly have like fourteen pixels for each dot. You need to either increase the Output Resolution, or lower the Screen Frequency.

Here is the res kept at 300, but the frequency dropped down to 16:

Increasing the Output Resolution will give cleaner looking dots. but will increase the pixel dimensions.
