Designing a "VOID" type background
I have a client who wants some gift certificates designed and wants there logo and/or the words VOID to be very faint but show up when copied like if you try to copy a check.
Is there some type of science to this?
My thinking and how I have it right now is the background is an 8% screen of PMS 300, the logo thing is over that at 12%. You can faintly make out the visual difference on a hard copy proof, and when I copy it, you do see these things popping out which is what they want, but not as drastic as I was hoping for like when you copy a check.
So is it something to do with the physical dot pattern itself? And if so how should I best design something like this?
I'm just using Indesign, does Photoshop need to be used as well to do something to this logo/Void part?
If anyone has ever had to design something similar, please share any info you might have that would help. Thanks

I don't believe the inks are what allows the void pantograph to work successfully. While there are inks with special security features (color-shifting properties, for example), the void pantograph is generally created using prepress software and requires specific line screens. A printer who specializes in printing the void pantograph would be a good resource - it sounds like it's not something you can create easily in the Adobe apps and expect consistent results on any output device.
Here's a thread with some discussion.

there is a special paper with the VOID pattern already in the background
BUT you can fake it
create the VOID art using fine solid lines that are vector art
how successful this will be depends on the output method of the original
if you use an offset printer it is easier to achieve as they can output finer lines which a copier turns into a solid background
try a 0.25 pt line separated by 0.50 pt of negative space then repeat the pattern of solid lines
you can make the lines wiggly, too
if your output device for the original is a xerographic process then you may need to increase your line to 0.5pt and your negative space to 1 pt

PLEASE HELP. How do you "create negative space"?
I guess that's not what I really meant to ask. You say ".25 pt line separated by .5 pt of negative space" and I don't know how to do that. Thanks!

negative space could be called white space - see the below V for one example of a way to make the VOID pantograph in a fakey way
when done from completely original art with solid fills the final product is printed with two different line screens
the non-void art would be printed at a nominal screen value (say 150 l.p.i.)
the VOID art will be printed at a very high screen value (say 250 l.p.i.)
when scanned or photocopied the 150 l.p.i. art will reproduce normally, because the scanning lens can see it normally. meanwhile the 250 l.p.i. art will fill-in because the scanning lens, and standard copier/laser printer cannot accurately render all of the fine dots - the dots bleed together and produce the highly legible, easily recognizable VOID type.

I was wondering if you still reply.
I am trying to make a void pantograph, but trying to use a different word instead. What program is good for making these?
Hope you are able to reply.

Making a Pantograph
A little research will show you that there are a large number of ways to create a pantograph on a laser printer. Patents are great for this. Take a look at Patent number 8,405,882. You’ll see that the basis behind the pantograph is the tonal weight. Here you will see that patterns have been created at the pixel level and then tiled onto the page. Where as you talk about two screens, a lower dpi for the word void and a finer one for the background. You can achieve this by making your own dots. A larger dot for the word void and a very fine dot for the background. The fine dots in the background make a kind of background shade. Today’s copiers work to remove that dirty background in an attempt to create a clean image. Imaging if you printed a document and the paper wasn’t a nice bright white. Without this ability the copier will make a grayish image of the document that you want to print. With all this said, yes your desktop laser printer can make a pantograph but don’t expect it to be of the quality of a printing house can produce. In addition, the quality of toner transfer is affected by weather, quality of toner, age of machine, cleanliness if the optics, and more. One other thing. If your planning on using this for a document that really needs to be secure – Don’t. If you can create the pantograph then that means someone else can recreate you work. After all the definition of Copy is “To Reproduce”. HP is also good enough to help us with our quest to make pantographs. See Links and have fun.

Thank you Mike30 for the response!
Do you know how to make this paper?
I'm actually new to any of the Illustrator or CoralDraw program.
People say this is hard to make, but I was trying to figure out first of all how to use the program itself.
Would you be helpful to guide me on creating this paper?
If needed, my email address is email@example.com

Thank you for your reply!
This is actually my first time making it for our small company.
Is making this paper hard?
I am trying to customize it using a specific word, but if I use professional companies, they charge me way too much. And I only need several papers.
Is there some steps you can guide me with if you have the time?
Or, if it is okay for you, I am willing to pay for you if you can make it for me?
Thank you for your time!
I will wait for your response.
