How many of us have heard or used the saying, “My memory is getting so bad that I could hide my own Easter eggs?” With everything that is always going on in our lives, I’m sure that we have all been there one time or another.
With Easter upon us, many children will be participating in the tradition of an egg hunt. Their parents, neighbors or adults will be hiding either hand colored or plastic eggs filled with goodies for the children to find.
Each of the hard boiled eggs will be dyed with a different color or design depending on the how they were decorated or the order they were dipped in the colorful tinted water. The vibrant colors changed drastically depending on which cup or bowl each egg is placed in first, second or last.
The same applies to the importance of reproducing a previously printed piece using UV technology. The ink sequence and lamp placement have a huge effect on the outcome.
You can go from blue sky’s to purple just by turning a lamp on or off in between certain colors. Have you experienced what happens to various Pantones when overprinting opaque whites cured at the unit printing the PMS color?
Many machines these days are sold with a reduced number of lamps. Not having full interdeck drying capabilities makes it even more important to know where the lamps were positioned for that previously printed job.
It’s not viable for a press operators to remember every form they run throughout a busy day. And for those multiple shift operations, it would be almost impossible to know how the other crews ran the job last. Why spend all of that wasted time trying to reinvent the wheel whenever you’re running an exact reprint?
I always stress the significance of “Repeatability & Predictability.” Reprints are no exception. The fact of knowing what results your going to achieve before you hang the plates should be straightforward. There should be no reason to struggle with reproducing a printed piece that you have previously run.
