Color Accurate Prints Without Color Measurement Devices

If you don’t have a color measurement device and your production uses on board generic driver or RIP settings instead of a custom ICC profile, skin tones are a great indicator of color accuracy as you test different settings.

Daily Maintenance

Each printer comes with maintenance instructions in the manual. Let’s be honest, though, we all use our printers at different workloads. Make sure you clean your machines on a regular basis (either daily or weekly depending on use). You should also check the alignment and registration before you begin printing on each media type. Each media type, thickness and smoothness will alter the media feed.

HPZ6100 Printer

We love our HP Z6100. It is a versatile printer that we use almost every day with media types ranging from coated bond paper to a thick poly/cotton canvas. However, we know this printer is a finicky machine. The trick is to have patience and follow the prompts step by step for each process. Trying to skip steps and trick the machine will cost you time in the end. Also, before closing the cover, make sure your media is lying flat and is properly lined up to avoid skewing and head crashes.

PERMANENT VS REMOVABLE Adhesive

We’re often asked what the difference is between permanent and removable adhesive. Permanent adhesives will generally activate on contact, making second chances for installation rather difficult. They also form a lasting bond, which means there is usually residue to remember them by if attempting to remove them. Removable adhesives are designed to come off with relative ease even after extended contact. And generally they remove with little or no residue remaining on the mounting surface. However, the longer a “removable adhesive” is left in place, the stronger the bond becomes. In other words, all removable adhesives eventually become permanent.

Preventing Head Crashes

Head crashes can have minor and major impact on your print production. Head crashes are most common in media that is overly thin (<4 mil) or overly thick ( >12 mil). The best prevention for head strikes is to be proactive. Feed the media out past the end of the platen by about six to ten inches. This is especially useful with solvent and latex printers that deliver extreme heat to the part of the roll that sits idle on the platen during the warm-up period. Another trick is to put weight clamps (something heavy enough to hold the media flat but not so heavy that it impacts the media feed) on the front edge of the media. This will assist the vacuum to keep the media flat against the platen, preventing the printer carriage from striking it as it travels back and forth. Balance the clamps evenly across the width of the roll to prevent skewing.

Roll Storage

It may sound silly, but the storage of media, especially media that you don’t use everyday, is very important. It is best to keep media inside the bag and the box it came in when not in use. This helps protect the coating and material itself from temperature and humidity changes that can degrade the coating and warp the media.

SOLVENT VS AQUEOUS Adhesive?

Solvent adhesive products tend to be more expensive, as the manufacturing of solvent based adhesives requires more stringent safety controls. However, solvent adhesives offer a more outdoor durable solution as the strength of their adhesive bond is not weakened by exposure to moisture. Solvent adhesives are really required for long term outdoor applications (>5 years) such as vehicle wraps. For a life expectancy less than 3 years, both solvent and aqueous adhesives will do just fine.

The Truth About Optical Brightener (OBA)

There are more myths than truths floating around the industry about optical brighteners and their impact on archivability. OBAs are not inherently bad and the presence or lack of OBAs does not inherently make something archival or not. OBAs do create the appearance of higher whiteness and richer printed colors. If unprotected, this will dissipate (fade) over a long period of time. In the case of canvas, the “faded” result will be similar to the original color of the base canvas. If you use a liquid overcoat, this will protect the enhanced whiteness and significantly minimize the fading over time.

Applying adhesive backed products

When applying adhesive backed products to walls, windows, floors or mounting boards, spending a little extra time cleaning and preparing the surface will ensure you get a good bond between your media and the mounting surface. Also, peeling back the release liner a little at a time, instead of all at once, will make the installation process easier and help prevent air pockets, fold-overs and creases.
