Get Good Results with VarnishIntroductionThe application of varnish to a print produces some spectacular, and at times, surprising resultsdepending on the combination of design and media. To achieve a smooth high gloss, varnishmust be applied in heavy coats. To achieve good results with varnish, consider the followingprinciples and tools:• Maintain a Clean Environment• Keep the Printer Clean• Prepare the Media Surface• Consider Varnish in the Job DesignNOTEVarnish does not require any special handling but, as with all inks, regular printheadmaintenance is important.Maintain a Clean EnvironmentAll inkjet printers are prone to image quality / jetting reliability issues when there is airborne dustor other debris that can interfere with the jetting of ink from the printheads. The air quality withinthe room is extremely important to the achievement of printed varnish images with minimal dustcontamination. It is also beneficial for maintaining the overall image quality and printhead jettingreliability.In the printer operating environment the amount of airborne particles can influence the finalvarnish finish. Since the systems that condition and circulate the air can also circulate dust andparticles, keeping the printer clean enough to produce good gloss varnish finish may requireextra cleaning. If you use the Varnish option frequently, we recommend that you take steps tominimize contaminants by isolating the printer from dusty conditions.Some tips for minimizing airborne dust and debris contamination:• Install a good ventilation system and diligently keep air filters clean.• Avoid dusty areas – printer should not be located near routers, sanders, trimmers or othermachinery that generate airborne dust and debris.• Do not install the printer on carpet or untreated concrete floor or other surfaces that can be asource of dust.• Avoid placing the printer near air vents.• Frequently wet-mop the room floor.Keep the Printer CleanSince the printer has moving parts (e.g., fans, carriage, gantry etc.) it is important to keep theseparts clean and dust free to minimize the risk of circulating airborne dust and debris anddepositing it on the media. Follow these tips for keeping the printer clean:• Keep the fan filters clean and replace as needed.• Wipe the bottom of the carriage clean with a lint free cloth.• Wipe (with a swab) the cut holes in the carriage pan around the printheads.• Wipe the external parts of the printer with a damp lint-free cloth: the table, gantry, carriageetc..Prepare the Media SurfaceVarnish can be successfully applied to most media. However, on some un-coated high-absorbentmedia, the varnish can be "lost" to the surface and it will be hard to tell that anything was applied.Get Good Results with Varnish170 Chapter 9 - Manage a White Ink Workflow
