The Future of Digital Proofing (4)

(6) The new IRISPROOFER series from SEGA is designed to replace the existing small format prepress proofing products REALST 5015 and 5030. It features high resolution, a single ink cartridge and ink and media for new printers. There are two types: one is 8 IRIS2PRINT and the other is 4 IRIS4PRINT. The IRISPROOFER series uses the continuous inkjet technology of the previous IRIS printer, but provides high resolution of 600 dpi in addition to 200 DPI, 240 DPI, and 300 DPI. Because IRIS uses the technology of micro-light spots to insert grayscale in the dots, making the text more sharp, and making the gradient color and image have higher quality, IRISPROOFER can provide users with better resolution than the low-cost 600DPI inkjet printer. . The IRISPROOFER proofing system simulates halftone screening on a 300 DPI printer. The single ink cartridge technology that SaiJing called IRISPEN does not place all four color inks in a single ink cartridge, and each ink has a single ink cartridge. This can not only facilitate maintenance, but also reduce the cost of ink consumption.
IRIS2PRINT and IRIS4PRINT were launched on the market in December 1998 at the same price as the previous PEALIST series, with another 40,000 USD and 60,000 USD.
(7) Screen Japan Screen launched a proofing system with correction function at the IPEX Expo in September 1998 to supplement the existing series. The first is the EF540J inkjet printer, which is a continuous tuner using a SILVER REED engine with a screen control system. The second is a proof correction system called PROOF EYE. PROOF EYE can identify the changes and differences between each proof and the previous proof. It can also identify errors in the text due to RIP's interpretation of errors or additions or deletions of text. It can also correct accidental errors in graphic images, variations in error pages, overprints and traps, or changes in density percentage. In and out corrections are PROOF EYE reading records in TIFF format, without output to film or photo paper. It can output correction results on inkjet printers such as FP540J or HP 750C, and can also display correction results on the PROOF EYE display.
(8) EVEREST launched by Agfa Agfa is developed based on the COLORSPAN engine. The print format can be up to 36 inches by 44 inches, and when printing 24 inches by 36 inches, it takes 15 minutes.
(9) Creo Creo introduced a digital prepress proofer with 4 open and multiple media: Creo TRENDSETTER SPECTRUM proofer has 4 open and split format, although it is still limited to use. IMATION MATCHPRINT LASER PROOF material, but the new KODAK print material used on the APPROVAL XP can also be imaged on this proofer. In addition, on TRENDSETTER 3230A, TRENDSETTER VLF and THERMOFLEX devices for the flexo CTP market, using a new Creo 40W imaging head can double the power of standard imaging heads, which can make Accelerated imaging of materials imaged with greater power expands the range of materials available.
2, double-sided large-format digital color pre-proofing double-sided large-format color proofer can print double-sided, has been spelled with a large version of the large-format color proofs with folding marks, mainly for CTP systems, can meet the layout Proofing needs, each product is mostly developed on the basis of HP inkjet printers.
(1) GERBR
GERBER developed the first double sided large format prepress proofing device in 1996. In order to support its CTP business, GERBER developed a double-sided large-format color pre-print proofing device using HP's color inkjet printer DESIGNJET. It can print full-color proofs that can be printed on both sides of large format and folded. GERBER uses a 34-inch wide (matching its GRESCENT/42 platesetter format) double-sided coated and punched paper with sprocket holes and manually flipped to print on both sides. Use 600DPI when printing black and white content and 200DIP when printing color. Printing time is approximately 10 minutes per side. Its color accuracy is sufficient for checking layouts, but it cannot match the color of prints. The device was priced at $35,000 at the time and proofing paper at $8 each.
(2) ESCHER-GRAD
ESCHER-GRAD introduced TRUEPROOFER, a double-sided wide-format proofing machine with two print heads in 1996. ESCHER-GRAD is an image-setter and direct plate-making machine development company. TRUEPROOFER uses two HP DESIGNJET inkjet imaging heads to print both sides of a system at a time. It can print large-format proofs that have been assembled in 8 minutes. To ensure maximum accuracy, ESCHER-CRAD has developed a drive system for rotary presses to maintain the alignment of the paper as it moves.
TRUEPROOF uses roll paper, prints the front of the first print, and then prints the back; while printing the back of the first print, it prints the front of the second print again. It takes about 8 minutes to print the front and back sides of a print. Alignment marks are also printed on the paper and these marks are scanned for alignment. In spite of this, the angular accuracy can only be 1/32 inch. TRUEPROOFERHP DESIGNJET ink can also use standard paper, but for better alignment, ESCHER-GRAD recommends using the paper it supplies. TRUEPROOFER sells for $60,000 when using the HP 750C and $75,000 when using the HP 2000. Full-format proof printing costs about $3.5-$5.00, depending on the amount of ink coverage, where paper costs about $2.5. (To be continued)
