Tips by stock type

Preprinted paper

	NOTE: When printing over offset inks, image permanence may be
	compromised.
	Table 3-16. Preprinted paper
Description	Any previously printed paper that will be printed on again. Examples of
	preprinted papers are forms, mailers and catalogs that will be personalized
	with customer names and addresses.
Selection tips	• Select papers printed with laser-compatible, lithographic inks to
	minimize offsetting. UV-cured inks are recommended, especially on
	coated stocks, to insure complete drying before printing on a Xerox
	Nuvera. Laser inks can be oxidative, or heat set types.
	• Do not use papers preprinted with xerographic processes.
	• Design the preprinted image so that no ink, varnish, or aqueous coating
	is placed in the area to be printed on by a Xerox Nuvera. Toner
	adhesion can not be assured when printing over inks or varnish. If the
	Xerox Nuvera image must be printed over pre-printed ink, results are
	more likely to be acceptable if the color is screened back to less than
	30% or the base stock is uncoated paper.
	• Select preprinted sheets that are free of excessive curl.
	• Select uncoated and coated papers that are laser compatible or that
	appear in the Media Compatibility Guide.
	• Select preprinted materials that are able to withstand:
	– Fuser temperatures of up to 437F (225 C) at 100 pounds per square
	inch for 29 milliseconds.
	– Exposure to fuser fluid.
	• Avoid cold set inks to prevent excessive offsetting.
	• Avoid conductive inks containing carbon blacks or metal powders.
	– Sheets will not hold sufficient electrical charge for proper dry ink
	transfer.
	– Paper handling problems may occur with conductive inks.
	• Test a small quantity of a preprinted paper before ordering a large
	quantity. However, if the guidelines provided here are not followed,
	results may be inconsistent.
	CAUTION: Never print on sheets that were printed with rubber-based inks
	or cured with a drying agent (starch, talc, or rosin powders). Machine
	contamination will result, causing background spotting, streaking, deposits
	in the fuser and/or spots on the photoreceptor.
	CAUTION: If you wish to use a preprinted paper that has not been tested
	by Xerox, check with your Xerox representative first. Some preprinted
	papers can cause production system damage.
Storage tips	Protect preprinted sheets from moisture to prevent image quality defects
	and feeding problems.
