ACCU Products FAQ
Check out some of our most frequently asked questions about our line of Accu products, including: AccuArt, AccuJet, AccuBlack and AccuInk.
- Check to see that digital artwork is of adequate resolution. Line art should be at a resolution of 1200 dpi. Color or grayscale art should be at a minimum of 300 dpi.
- Check to see that you are printing at a proper resolution. Positives should be printed at a minimum of 720 dpi. 1440 dpi is recommended.
- Be sure to choose a film media from your printer properties menu. This tells the printer what type of media is going through the printer.
- Are you using a RIP? The RIP typically will improve print quality, resulting in smoother line edges and clean halftone dots if you’re doing separations. The AccuArt films can handle halftones up to 65 lpi.
- Make sure that you printed on the coated side of the film.
- Did you use the proper print settings? For best results, print at a resolution of 1440 dpi and use a print setting for film media. You may need to experiment to find the best media setting for your printer.
- If you’re doing positives/negatives, print with black ink only versus color. If you’re in color mode, sometimes the printer will mix the colors to make black opposed to getting a pure black ink print.
- Make sure that you’re using dye-based inks. The dye-based inks penetrate into the film, yielding better density. Pigment based inks will remain on the surface which will typically yield less density.
- Equipment cost is a lot lower. Inkjet printers are relatively inexpensive, and typically cost a fraction of what laser printers and imagesetters cost.
- Accu Products are clear films with excellent density, which means that they will properly expose your screen. Vellums and some other media, are more opaque in nature, which means the light will not transfer as easy during exposure. This will sometimes result in underexposure. Another concern is often the toner (black) areas of the positive are not opaque enough to block out light. This may cause light to transfer through these areas, leading to improper exposure which may yield imaging and washout problems.
- Inkjet printing is a cold process. With laser and thermal printers, heat is involved in the process which can cause image distortion and shrinkage of the media. Yellowing is particularly evident with thermal printing.
