Technical Service FAQs

What is the shelf-life of YUPO paper?

The shelf life of YUPO® products varies based on factors such as application, storage conditions, and format (roll vs. sheet). Therefore, it is challenging to specify an exact shelf-life period. As a best practice, we recommend consuming stock on a first-in, first-out basis, using the delivery date as a reference. Generally, you can expect a minimum shelf life of one year from the delivery date, provided the product is stored in its original, unopened packaging and under warehouse conditions not exceeding 120°F. If the product has been opened and needs to be stored again, ensure it is properly resealed. For stock that has surpassed this time frame, it is advisable to verify its performance for your specific application or contact our Technical Service Department at (888) 873-9876 for assistance.

How can we control static when printing on YUPO?

To avoid static, maintain at least 42% relative humidity. Also, use static elimination equipment such as ionizing air units or static elimination bars at the feeder and/or delivery. Contact SIMCO or other manufacturer for additional information on anti-static equipment.

YUPO ACCEL® is whiter.
YUPO ACCEL® is brighter.
YUPO ACCEL® is glossier.

How can we minimize dust build-up?

Dry dust on open unit.
Minimize impression pressure.
Print with yellow down first to minimize effects of dusting.
Use coarse blankets versus super smooth.

How can we eliminate set-off?

To avoid set-off, use a good amount of spray powder to reduce the contact between the printed sheets and improve the airflow in the load which will allow the ink more time to dry.

Racking lifts no higher than 3-6 inches (depending on ink coverage) will prevent the weight of the lift from causing set-off to the printed sheets.
Prevent static from occurring. (See: “How can we control static when printing on YUPO?”)
Move / Air the printed piles of YUPO with care.

Can I combine printed YUPO with another substrate?

Yes. However, if YUPO will be combined with another substrate, you should print the entire job (YUPO and other substrate) with inks formulated for YUPO.

Is die cutting possible on YUPO?

Die cutting can be performed on YUPO as long as the blades to be used are sharp and free from nicks. Also, cutting right angles and internal sharp corners on YUPO will cause tearing, so be sure to radius the die. (1/16 inch minimum)
