Thin papers require more thought than their thicker kin because thin papers have much less fiber content. Lower fiber content requires a thinner ink application to ensure the paper can dry and does not cockle. For papers of 45# and less, solid ink color areas can cause paper fiber to swell in the print area and actually fold up on itself during web printing. This can cause web breaks and, if these folds go through finishing equipment, jams are inevitable. Just turn up the heat you say? Adding heat or increasing airflow and blasting the paper can cause saturated paper fibers to dry too quickly and shrink. This can also cause the paper to fold over on itself and, when it dries out too quickly, become brittle within the printed. This can also result in web breaks or cracks on folds. Anyone who has ever had to re-web a high speed production inkjet machine knows it is time consuming and frustrating. Production Tip: Always manage ink volume before adjusting heat settings. It is easier to get your heat settings dialed in if the proper amount of ink is applied.
