Hi all,
I am currently puzzled how to create a pantograph with the word VOID written.
I tried to create one and it is attached as PSD file but i am unsuccessful in the matter.
It has to be back and white in color or a combination of magenta.
Any advice or lead in this would be highly appreciated.
Thanks in advance
It has been over 30 years since I did these, I have probably forgotten a lot...
A sample image link follows. Flatten the linked sample and convert to bitmap mode at 2400ppi using 50% threshold method.
Test print at the highest resolution available at 100% magnification/same size.
This uses a background "stipple" of 45° round dots at 120 lpi frequency.
The text is using a "line" pattern at 45° at 120 lpi frequency.
It will take a lot of experimentation, trial and error. It will depend on your out
...I have created an action to help those that are having problems creating the pantograph image. Ideally this would be created in Workflow/RIP software and not in Photoshop.
One can adjust the size and resolution of the background image, however, I'd recommend working at 1200ppi or 2400ppi. 600ppi may be too low, however it would depend on the output resolution.
One can also adjust the text content, size and positioning.
You can download the action from my dropbox here:

My first use was originally for film exposure on a laser imagesetter, exposing an aluminium offset printing plate in a vacuum exposure frame... So it is independent of the technology, with the caveat being the resolution requirements for creating consistent clear dots and lines.
Using an inkjet has challenges, I'd recommend a symmetrical resolution of say 1440x1440 or greater, you need the best output that a device is capable of.
