What is the difference between thermal and Piezo printers?
Thermal inkjet (also called bubble jet) has a print head that projects the ink droplets by heating the ink, while Piezo printers eject the ink by an electric impulse to a piezo transducer.
What is the difference between water based, pigment, and solvent inks?
Most of the inkjet printers use water as the ink carrier. Aqueous inks are either dye based or pigment based. Solvent inks contain alcohol instead of water and edge their way into the media and produce a more permanent image. Aqueous inks are used in thermal printers while the solvent inks are used in Piezo printers.
What factors affect the drying time of the image?
First check the compatibility of the media to see if it is recommended for the printer and ink. Other factors affecting the drying time are high humidity, low temperature, and too high an ink level.
What are the factors that influence image life?
The best way to achieve maximum print life is to use pigment ink. Other factors affecting print life are exposure to light, temperature and humidity, and contaminants in the air such as ozone. To extend the life, laminates with UV inhibitors should be used.
What are large format prints?
Generally, anything larger 24in wide.
Are sample rolls available?
Yes, contact your nearest Dietzgen dealer.
How do I handle Ink Jet media before and after printing?
- Store unused media in original packaging
- Allow media to acclimate to the environment before use.
- Avoid touching the print side by handling the edges of the roll
- Avoid any finishing until prints are completely dry
- Do not allow the printed side to come in contact with itself

|FAQs – SPECIFIC PRODUCT QUESTIONS
Will Dietzgen’s media work with my printer?
Check the compatibility chart provided by Dietzgen.
What affects image quality?
There numerous factors that affect image quality among these are but not limited to separation of the process ink colors of cyan, magenta and yellow as well as black; coated or non coated media; ink level; print resolution; image line edge; grayscale response and image permanence.
Can dye based inks be used on outdoor media?
Yes you can but the image life will fade quicker. To extend the image life use a laminate.
What are the differences between cast vinyl and calendared vinyl?
Cast vinyl is made by a process of pouring liquid vinyl into a mold to a desired thickness and let it harden. Calendared vinyl is a process by squeezing vinyl material between two pressurized rollers to the thickness desired. Cast vinyl is more expensive but also dimensionally more stable. Most vinyl media is calendared vinyl.
How do I prevent cockling in uncoated bond media?
Reduce the ink level to a degree that prevents cockling. Alternative, use a heavier paper weight.
What is the cause of photo base media curling?
Lack of humidity causes paper media to curl. The environment needs to be controlled between 30-70% humidity.
What should I do if profiles are not available for my media?
General profiles are available in your RIP or on your printer. Find a media setting corresponding to the media you are using and tweak from there.
How can I prevent banding on my print?
Banding can occur by using a media that is not compatible with the printer and ink combination. The printer needs also be calibrated for a particular media. Printer must also be set for the best profile. Banding can also be caused by clogged nozzles on the print head.
How can I get maximum durability from my inkjet print?
The maximum image life can be obtained by using pigment inks with a recommended media. To further extend the life use a UV laminate.
Are there any special requirements for the media waste?
Generally there are none. However, it is always best to dispose of waste in accordance to local requirements.
Do I need Material Safety Data Sheets for media?
No Material Safety Data Sheets (MSDS) are required for media. Media is considered an article which is exempt from MSDS.
How can I useclear film on the HP 500, 2000, or 3000 printers?
These printers have an optical sensor that can not sense the clear film. A white paper interleave is required for the printer to sense the edge of the clear film.

|FAQs – FINISHING
What are the general guidelines during finishing
- To counteract roll memory, reverse wind media when it is completely dry
- Do not allow media to be rolled up for a long time
- When rolling up media use the largest diameter possible.
- Prints should be flat and rough trimmed before laminating.
What is the difference between pressure sensitive and heat activated laminates?
Pressure sensitive laminate have an adhesive and release liner and can applied to the media by pressure only. Heat activated laminate does not require a release liner and is applied to the media with heat and pressure. There are two types of heat activated laminate, one considered a high temperature 220-240°F and the other low temperature less than 180°F.
How long should I wait after printing before laminating?
The image needs to be thoroughly dry before laminating. Generally, take at least 30minutes. To assure a completely dry print, wait until the next day before laminating.
What type of laminate should I use?
Check the specifications of the media you are using.
Do laminates increase image life?
Laminates with UV inhibitors can increase image life up to 3 months.
How do I prevent tunneling on rolled up media?
Media that is laminated and rolled up should be rolled up with the image side “OUT”.
Should banner material be laminated?
In general, banner material should not be laminated. If additional protection is desired, use a UV inhibitor spray. Make sure the spray is compatible with the banner media. Test before use.
How should I insert grommets in banner material?
Grommets should always be installed in folded edges. For extra strength, fold the ends twice for four thicknesses.
How do I keep out dust trapped under the laminate?
Contact the laminator company and purchase a cleaning roller. The cleaning roller will remove dust, lint and other contaminants.
How do I prevent bubbles or ripples when laminating?
Make sure the setting of the laminator matches the laminate (temperature, webbing, pressure of the rollers and supply roll tension).
How do I prevent outside banner media from blowing away?
Wind slits should be cut into the banner media if the banner is outside in windy condition.
How do I apply adhesive media?
The surface must be clean, dry and smooth before applying. Start in the center and press to the outside.
