Don’t Limit Your Toolbox!
Imagine trying to cut your entire lawn using a weed whacker or bush trimmers. Better yet, how about attempting to repair that leaky kitchen faucet with a pair of pliers and a screw driver?
How many hours on the weekends have you spent taking care of miscellaneous projects around the house? Whether it’s something as large as laying a new ceramic tile floor in the foyer or as small as hanging a new plasma television in the family room, during the project I’m sure you wished that you owned or rented a wet saw or longer drill bits. Or maybe a strap wrench to get to the pipes under that kitchen sink.
These sorts of household tasks are so much easier if you follow the maxim: “The right tool for the right job.”
Don’t limit your toolbox!
Keep all of this in mind when you’re looking to successfully pull off that specialized coating request for a new or current customer.
For Anilox rollers, one size doesn’t fit all!
You have to remember how an Anilox roller functions. Its only purpose is to transfer a variety of coatings from the chamber to the blanket and then to the substrate. There are three factors to take into consideration when determining the proper engraving specifications—the angle of the screen (normally 60°), the LPI (lines per inch) and the cell volume. The cell depth or volume and LPI numbers usually combine to determine the visual lay and the amount of coating transferred onto the substrate.
When you’re attempting to run everything from standard aqueous coating through a special effects UV coating, no one roller will give you the optimum results. You have to determine what specifications are needed for the types of coatings you’re going to most run. It is not uncommon for printers that run a variety of coatings to have numerous screen configured rollers on the shelf for those special needs.
Many pressrooms start out with a banded roller that consists of multiple screen configurations engraved into the surface of one roller. This not only saves a great deal of time, but also money. It gives you the option to determine the optimal engraving for your supplies and desires without the expense of multiple roller purchases. When testing is complete, you can then have it re-engraved to the best results.
Keep all of this in mind when making that initial purchase or when you want to take a shot at that special project.
