Common print quality problems and how to identify: - Offsetting: The appearance on the printed sheet of an image from the opposite side of the sheet. Offsetting can happen because of excessive ink, insufficient dries in the ink, or cutting the job when the ink is still wet. - Picking: White areas that look like snow where ink and some of the paper has been pulled off the sheet because the ink has too much tack. Can also be caused by a poor quality paper. - Hickeys: White circular patterns created by lint or other contamination on the plate or blanket. Most noticeable on large solids. Hickeys can be controlled by an experienced press operator. However, not entirely eliminated in pieces with large solids. - Muddy or uneven screens: Most often occurs due to dot gain on porous or lower grade papers. Can also occur if rollers are in poor condition or ink is run too heavy. - Ghosts: Faint images in areas where they should not appear, or lighter areas where there should be even ink coverage.
How to save money when ordering printing: - Combine jobs: When possible, order jobs that have common colors at the same time. This can often eliminate charges for color "was ups" and in some cases jobs can be combined into a single run if the papers are common. - Right source for the job: Certain jobs are best run on copiers, digital presses, web presses or offset presses. Rely on a reputable print expert, such as Clarence Printing, to find the least cost alternative.
