The answer will be different in every plant. If you ran the calculation program on our home page, you saw that we made four assumptions:
- If a color is wrong on press, you can correct it in 15 minutes.
- While an ink formula is being adjusted, the press is running at 1/4 speed.
- 2000 hours annually per shift.
- Your plant has only one press & no Sunday drive.
Let’s see if we can come up with some numbers that are more specific to your operation. This form lets you input ink correction times and press speeds that might be more appropriate for your plant.

A properly implemented Perfect Proofing System should impact your materials costs as follows:
|
How much did you pay your ink vendors last year?
Annual Ink cost |
$ |
|
SAVINGS from Ink Not Used while inks are being adjusted. |
$ |
How much did you spend on stock last year?
Annual Stock Cost |
$ |
|
SAVINGS from Stock Not Used while inks are being adjusted. |

The Perfect Proofing System also converts downtime spent correcting inks into productive hours. Your input creates the following projection: |
Throughout the year, how many shifts do you average per day?

Notes: The calculations run on this page are based on these three assumptions.
- Normal press make ready time has not been taken into account by this calculator. Therefore, the savings generated above should be considered conservative. Your Integrity Engineering representative has a more sophisticated program that he will be happy to run if you want to investigate further.
- 2000 hours annually per shift.
- No Sunday drives.
