Staccato is our standard at Vision Graphics
Kodak Staccato® produces high-fidelity, artifact-free images that exhibit fine detail, without halftone rosettes, screening moiré, gray level limitations or abrupt jumps in tone — all without impacting RIPing or rendering time.

Typical commercial printers use a screen frequency of 150 to 175 lines per inch. Vision Graphics' Staccato implementation resolves images and page elements to 20 microns — roughly equivalent to a conventional 340 line screen. But that's not where it ends.

Staccato improves color and halftone stability on press, making it a perfect complement to consistent high quality sheetfed printing. When imaged with consistency and accuracy of Creo's SQUAREspot® thermal imaging, Staccato screening delivers unmatched quality to proof and plate, making high fidelity screening a practical tool for Vision Graphics' pressroom.

Increased stability means more vibrant, more predictable color
Staccato screening brings tonal and color stability to the pressroom by reducing variations in dot gain caused by changes in solid ink density, wet trap, and color contamination from paper. The pseudo-random nature of the Staccato halftone patterns also means that misregistration does not degrade the look of the halftone, nor cause overall color shifts in presswork. Unique halftone patterns are used in each separation to minimize dot-ondot printing. The on-press stability of Staccato makes it particularly effective for replacing custom colors with process screen builds.

Greater gamut and continuous-tone quality
Staccato produces high-impact, artifact-free images with greater image fidelity, richer colors, open shadows, sharper texture and finer detail. It eliminates screening moiré, rosette patterns, shade stepping, and abrupt tone jumps. Staccato screens absorb light more efficiently and produce midtone vibrancy and gamut that is not possible with AM screens. Staccato screening provides near-photographic quality, protects the purity and saturation of colors, and subdues color inconsistencies caused by paper substrate.

Predictable Spectrum proofing
Staccato can be reliably proofed on Creo Spectrum digital halftone proofing devices, as well as proofed for color on Kodak Polychrome Matchprint Inkjet proofer.

SQUAREspot thermal imaging for reliable screening
Conventional filmsetters as well as computer-to-plate (CTP) devices, require a level of process control in imaging, proofing, plating and processing, that makes it difficult for many printers to deliver consistent results with the very fine dots used in high line screen and stochastic halftones. These issues are overcome by Creo SQUAREspot thermal imaging—the foundation for accurate and consistent presswork in all production conditions. With SQUAREspot, Staccato’s fine dot structure becomes reliable and practical for routine daily production. SQUAREspot delivers end-to-end imaging integrity from the original file through to the press despite natural imaging variables such as laser power, plate emulsion sensitivity, and processor variation.

Smooth tints and quarter-tones for noise-free print
Staccato screens overcome the problems with graininess and visible artifacts in flat tint areas that are commonly associated with traditional stochastic/FM screens. Staccato dots are clustered into orderly patterns to eliminate low-frequency noise and inconsistencies that lead to visibly grainy patterns.

Print on more materials, using thinner ink films
Staccato prints with thinner ink films, making it ideal for printing onto a wide range of substrates including fine paper, uncoated stock, recycled paper, newsprint, plastics and metals. Shadows can be held open without sacrificing solid ink density, contrast or gamut. Thin ink films dry faster than AM screens, which improves performance on perfecting presses, reduces drying time with less setoff, and may help speed up work in progress and reduce time to bindery.

Ensure consistent, stable printing
Staccato’s microdot structures carry a thin ink film through most of the tonal range, substantially reducing the variation in mechanical gain common to AM dots. Dot gain in Staccato printing is primarily optical, not mechanical. Lower mechanical gain means less variation as inking levels and paper characteristics change on press, resulting in more reliable and predictable color. Compared to images screened with AM screening, Staccato images are not susceptible to a visible change in the halftone structure and color when misregistered, further improving overall stability. In addition, the fine dot structure absorbs light more efficiently, resulting in less color contamination from the underlying paper.

Optimized screens for print, proof, and tone control
Staccato is optimized for printability and smoothness. Unique halftones are used in each separation. To ensure consistency, the dot patterns are built-in and deliver the same pattern every time they are imaged. Pre-defined calibration curves help normalize dot gain to standard printing conditions. For custom print requirements, Staccato can be optimized with the Harmony™ tonal calibration utility in Prinergy® and iMPAct workflows, or with tone reproduction curves in the Brisque™ workflow software.

Simplicity for workflow integration
Staccato is applied and calibrated in prepress in the same manner as other halftone screens. Staccato is controlled from Prinergy and from desktop applications that can assign screening to PDF and EPS images, pages, forms, and individual separations. Its use has no effect on RIPing or rendering time.
