Kodak 8mil manual Handling, Curl, When printing, During finishing

•Print at slower speeds. This will cause less static buildup and make the marks less noticeable.

•Add a 1% or higher fill color for CMYK in white areas; the exact amount to be determined by testing in your working environment. It has been demonstrated in a 30% RH environment that filling white areas with a 1% dot for all 4 chanels, C, M, Y, and K, will virtually remove the marks. The resulting light gray in white areas is not objectionable, especially when prints are trimmed so that no unprinted media is visible as a reference. The fill color can be added in the application that the file was created in or within your RIP software. In ONYX POSTERSHOP, simply use the "Replace Color" tool, select white, and add 1% to all 4 colors.

Caution

Caution

When using film based medias on printers in very low humidity conditions, 30% or lower, static charges may be enough to damage your printer. It is not recommended that you print in these conditions. Be sure to follow your printer manufacturers guidelines for operating conditions, which are especially critical when using film based medias.

HANDLING

All inkjet media must be handled with care before and after printing to prevent damage to the ink receiving layer and printed images. Use the following guidelines, your experience, and common sense for the proper care of your media.

•Store unused media in its original packaging, using the core-plugs and plastic sleeves.

•Allow media to acclimate to your environmental conditions for at least 24 hours before use.

•KODAK inkjet media is rolled printable side out. Avoid touching the printable side by handling by the edges of the roll.

•Wear cotton gloves when handling media to avoid scratches, abrasions and fingerprints from moisture and oils on your hands.

•Do not allow the media to come into contact with moisture. Moisture will damage many types of inkjet medias before and after printing.

•Avoid handling, trimming, laminating or other finishing until prints are completely dry. Dry times will vary based on media type, ink type and environmental conditions.

•Do not fold, bend or crease media or damage may occur to the ink receiving layer.

•Do not allow the surface of the media to come into contact with itself or another inkjet media.

•Use media only in recommended operating conditions—see "Physical Characteristics" section.

Curl

Most types of roll-based inkjet media will exhibit some amount of curl, either toward the base side or toward the print side. This will vary based on media type and environmental conditions. Some media will curl more in low humidity environments and others in high humidity environments. Also, media may curl more towards the core or end of the roll due to "roll memory."

Although curl is mainly an issue when printing, it can also have an impact on laminating and other finishing procedures. Follow these guidelines, and use your experience and common sense to avoid issues caused by curl.

When printing:

•Advance media several inches past the print platen before starting a print job.

•Add weights or clips to the leading edge of the media.

•Attach media to the printer’s take-up spool before starting printing.

•Adjust vacuum settings accordingly on printers equipped with variable media vacuum settings.

•Adjust heater and dryer settings on equipped printers to obtain optimum conditions to ensure flat media. See printer owners' manual for their recommendations.

During finishing:

•Reverse wind media, when completely dry, to counteract roll memory.

•Do not allow media to remain rolled for extended periods of time.

•Rough cut prints and lay them flat before laminating.
