Current Model 508 -> 518
The X-Rite 518 Spectrodensitometer combines everything you need for exceptional 4-color proofing and pressroom quality control: spectral accuracy, a full range of functions, efficient operation, and hand-held convenience.
The X-Rite 518 Meets The Needs Of Any 4-Color Pressroom
The X-Rite 518 excels at quality control for all 4-color printing operations, including sheet-fed, web press, publication printing, and newsprint. At the touch of a button, you get density, dot, trap, print contrast, hue error, or grayness information, all of it calculated with spectral accuracy. The hand-held, portable design goes anywhere to quickly take measurements and deliver the data you need to keep your presses on target.
Special Electronic Function Selection Feature
With each reading along the color bar, the 518's Electronic Function Selection (EFS) feature automatically identifies whether it is a solid, tint, or overprint. It automatically displays the correct reading and color being measured. EFS allows an operator to read an entire color bar in seconds. It also reduces guesswork and helps you finish your print jobs more efficiently.
Our standard pressroom densitometer is essential for 4-color press operators. Use it to help determine which press adjustments need to be made during the run.
- Trap feature helps quickly determine whether on-press color shifts may be due to ink rotation or tack using
- Check for ink consistency through the run with hue-error and grayness features - evaluate the extent of color contamination or dirtiness
- Establish optimum density levels and objectively assess shadow detail with industry-standard print contrast feature
- Quickly and easily measure any color bar - the built-in EFS function selects the proper feature (density, dot, trap, print contrast) based on the patch you measure
- Upgrade using a keycode to add new features like color or spectral data
- Only X-Rite lets you select a measurement aperture - microspot 1.6 x 3.2 mm, small 2.0 mm, medium 3.4 mm or large 6.0 mm
