Proof selection

Coverage proofing

Imation Colorkey, Fuji Fuji Proof, DuPont Cromacheck.

Although coverage proofing is a technology that is declining, it still occupies a certain market share, such as screen printing, packaging printing, and the traditional market that needs to display spot colors on film proofing. The advantages of overlay proofing are quick and easy, and you can see the color break down.

Single proof/membrane proofing to be flushed

Imation Matchprint, Fuji FujiProof, DuPont Waterproof, and Cromalin.

Leaflet or pellicle proofing is usually a contract proof produced by special specifications such as SNAP, GRACOL, and SWOP. They are still the most common contract proofing, and in many cases the most economical, in addition, single proofing throughout The market for proofing still holds the largest share. We began to see this market stop growing and we expect to gradually decline in the next few years. For many small and medium-sized users who need halftone proofing, single proofing is still the preferred contract proofing method for the next few years.

Dry proofing

Agfa Pressmatch Dry Neg/Pos and Pressmatch Dry News dry sheet proofing is the latest in the simulation proofing market. This new technology enables proofing users to increase productivity and reduce costs, so it is still able to simulate proofing in recession. The market has a large share.

Benchtop Inkjet Proofing - Epson5000

Due to the low cost of materials for desktop ink-jet printing and the high flexibility of imaging, benchtop inkjet proofers designed specifically for the graphic arts industry are expected to be very popular, especially for new users. But they need to provide higher quality, faster speed and higher consistency than they are today. They will not replace potential sublimation proofing but will reduce its popularity.

Sublimation type proofing

Imation Rainbow, Kodak DCP9000, DuPont PreView, Tektronix Phaser, Fuji FirstProof, NweGen ChromaxPro, Seiko (sublimation). Thermal Sublimation Proofing A continuous proofing technique that can achieve near-photographic quality, 300-400 dpi, less equipment investment but higher consumable cost. This mature technology will remain commonplace in the design world where photo quality is required. However, other technologies with lower cost and the same or higher image quality will eventually eliminate heat sublimation.

Hot-stud ink jet laser print soft proofing Pre-press concepts and content are converted into unpatched analog or digital format manuscripts for use in making plates.
Preflighting verifies the final verification of the integrity, completeness, and accuracy of the file before electronic imposition. Laser Print Page Proofing Color Proofing Colors and content are evaluated using four-color proofing. Confirm the received electronic data. Check location, layout, etc. Can also be used to show last minute changes. Cover proofing ink jet contract proofing is hard copy. Show how the image will be reproduced in the final proof of the print. Once the customer approves, this proofing becomes the actual contract for the printing room based on the guidelines. This is a confirmation of the prepress work. Single proofing to be flushed

Dry proofing

High resolution inkjet

Halftone Digital Proofing Digital Hardcopy Contract Proofing Here a hard copy proofing can be performed in the CtP workflow. If the same RIP technology is applied to the printing plate, this proofing can predict any change from the original contract proofing. Halftone Digital Proofing Electronic Imposition Imposition Proofing Before the CtP plate imaging, check the correct imposition, page number, mark, etc. Sample wide-format inkjet that can also be used for complex document binding

Wide-format inkjet proofing

Agfa Sherpa, DuPont Digital Waterproof, Polaroid DryJet, Scitex IRIS, etc.

Ink jet is the direct spray of ink on paper, there are two ways: continuous inkjet, which makes the ink point continuously and directly to the paper, and the unwanted ink out of the target.

Drop-on-demand (DOD) uses piezo or thermal technology to create dots where needed. It is expected that on-demand inkjet technology will become the main inkjet technology in the market.

The inkjet technology is characterized by low initial equipment investment, excellent quality of continuous image adjustment, flexibility in material selection, and low material costs. The strong promotion of the offensive and the many advantages of inkjet will make inkjet technology the main technology for continuous color proofing. Depending on the application, these inkjet devices can be used to make mid-color proofing, contract quality proofing, or imposition proofing.

Halftone digital proofing

Polaroid PolaProof, Kodak Approval Imation Matchprint Laser.

There is a potential market demand for affordable halftone digital color proofing equipment, especially those that can use the same RIP as CtP equipment. The rapid growth of CtP has made the need for low-cost half-tone digital color proofing more urgent, replacing film-based color proofing. It is expected that new digital half-tone proofing equipment will emerge from the market to meet these requirements, making this technology a widely accepted method.
