Part Three – Custom Butterfly Edge Guards for HP Latex Printers

HP Latex Specialist Timothy Mitchell works with many different brands and types of media, providing him the unique opportunity to help printer operators find answers to some recurring issues – head strike or media curling, to name a few – that may occur.

Mitchell noticed that when he printed on high-intensity prismatic or reflective media and other heavy-duty products that retain curl, the edge guards weren’t properly holding the print in place as it was feeding through, causing it to raise up and contact with the carriage. When that happens, the image can be damaged, which means the graphic must be reprinted.

Reprints are a waste of media, ink and time. Mitchell found that creating a double – or butterfly – edge guard means the media stays closer to the platen, reducing the chance that the print will come in contact with the carriage.

“The reflective films tend to be expensive and when they go through the printer, I don’t want to waste anything,” he says. “They tend to curl a little. I need a little more strength to hold them down after they go through the original edge guards.”

In the video above, Mitchell explains how easy it is to make these guards: “You need to order an additional set, take them apart and put them back together.”

Part Two – Using the Counterweights and Take-up Reel on Your HP Latex Printer

Printing panels for trade shows can keep a latex printer and a production manager busy, but there is one tip from HP Latex Specialist Timothy Mitchell that can help lighten the load a little: use the counterweights.

“There are a couple of key pieces to successfully panel printing with the 300 series latex printer,” Mitchell says of the counterweights. If you’ve never used them, they could still be on the dancer bar for the newer 300 series printers. For the older models (310, 330, 360), you may need to contact HP Support to order a set.

When panel printing, it is more efficient and accurate to reduce the tension on the media. The dancer bar adds tension and adjusting the counterweights on either end of the bar allows you to increase or decrease the tension, depending on the media thickness and material.

Another important tool to use properly is the take-up reel. Many people may not know that there is an option to wind the graphics inside or outside.

“If you go inside, there is a little less tension than if you go outside. I usually judge it by the media,” Mitchell says.

Much like adjusting the counterweights, winding media inside or outside depends on the media.

Watch the video above to see Mitchell discuss his tips and tricks for the counterweights and take-up reel. If you have an older 300 series printer, you can contact HP Latex Support.
