Corrugated Plastic Also known as: corrugated or fluted polypropylene Brand name examples: Corflute®, Coroplast®, Correx® Preparation  The quality of corrugated polypropylene can vary greatly. A corona treatment is generally applied when manufactured to increase the surface tension for better ink adhesion. This corona treatment will diminish over time. Material that has be shipped long distances or stored for an extended period of time will have more problems with ink adhesion.  This material tends to hold static charge - avoid sliding the media from the stack or carrying across carpeted surfaces.  Review and follow the steps in the Static Electricity chapter of this guide.  Ensure that media tables are attached and secured to the printer to provide a grounding path for static loaded material.  Media is often supplied un-square, so trimming it to square may be necessary for some applications, such as edge to edge printing. Make sure all edges are cut clean and are free of burrs and/or excess material.  Wipe the printing surface with an anti-static tack cloth to remove static charge and any dust or debris.  If an anti-static tack cloth is not available, 90% or higher IPA on a lint-free cloth can be used to remove dust or debris. Allow the sheet to sit out on the input table about 5 minutes to allow the IPA to evaporate and the static to dissipate. Recommended print modes  Depending on application, ink coverage and image content, all print modes may print acceptably.  Faster print speeds can be obtained without noticeable banding by feeding the media with the flutes in parallel with the printhead carriage motion. Printing      Select Corrugated Plastic when configuring and loading this media. Non-white media may not be able to be detected by the onboard camera. If so, create a copy of the Corrugated Plastic media using the Media Wizard and change the Detectable by Printer option to No. Use the lowest possible UV lamp power setting to cure the ink. Media is heat-sensitive. It may require a higher vacuum setting, faster print modes, higher than standard head height, and printing delays in some combination to achieve best output. Use a Corrugated Plastic media profile from the RIP software. Output handling  Ink adhesion improves over 24 hours. Sometimes it is beneficial to wait 24 hours before cutting full-bleed prints. 15
