Veripress is an on-press softproofing solution, representing the next generation in digital proofing. Built around an advanced colour management system with a touch screen interface, Veripress uses platesetter RIP data to produce verified colour-matched proofs on screen, at the touch of a button.
In an era where the productivity demands of high volume press environments means less time available for hardcopy proofs, softproofing is the logical solution. Fast, cost efficient and easy to use, Veripress ensures proofs are ready on the press as soon as the plates arrive.
The Veripress range has integrated softproofi ng solutions suited to any production and press workflow. Press versions can read the native file format, directory structure, plate assembly and imposition data of all major manufacturer proprietary RIPs.
Colour Management and Multicolour Support
Veripress is built on a full 16-bit engine. The colour management system is ICC v4.2 compliant and capable of reproducing the gamut of virtually any print process on screen.
Full multicolour support provides accurate proofing of any multicolour printing process – be it hexachrome, 7-colour or a custom process. Support for unlimited spot colours means precise proofing for even the most complex jobs.
Using Bookfilter, operators are able to proof large multi-section or multi-edition publications, newspapers or magazines at the touch of a button. Pages used in multiple publications need only be RIPped once for proofing. Veripress reads the same planning files used on the press to assemble pages in the correct sequence for each publication to be proofed.
Veripress includes out-of-the-box support for touch screens – the press room is no place for a mouseor keyboard. The Veripress touch console interface features hierarchical one-touch access to all proofing and navigation functions. A visual pan interface displays a thumbnail of the currently loaded proof. Navigation to a part of the page is as simple as a touch or drag.
Flipbook uses 3D viewing technology to allow a publication to be previewed in its final printed form. Any newspaper or magazine job can be loaded as a virtual book, quickly flipped through by a press operator, and checked for correct de-imposition, page order, orientation or duplicates. Books can be flipped in left-right or calendar mode, the zoom and viewing angle adjusted and if required the whole publication can be exported as a PDF or QuickTime movie.
The virtual Loupe tool allows for the magnification of sections of page and provides accurate readings of dot percentages. A touch-and-drag interface moves the Loupe around the page and allows the loupe size and magnification to be adjusted while examining halftone dots and fine text. Channel controls cycle the view within the Loupe through the area’s individual ink channels.
A dynamic heads-up-display shows the ink dot percentages at a pointed centred crosshair or within an area average percentage box configured to the line screen of plates.
The Channels widget will pop up a window listing all channels within the job and checkboxes to tick/untick to show the various channels onscreen. The virtual Loupe will allow you to cycle through the various channels using the arrow keys without having to open the Channels widget.
Ink Key Viewer
Ink Key Viewer aids the press operator in the initial setup of press ink ducts. Plate size and the number of ink keys are stored in the Press configuration and are automatically applied to the view. Jobs can be viewed independently or positioned on the plate displaying the relative ink use for each ink key. The amount of ink used by the print run can be calculated instantly by entering the number of prints and the ink weight (in g/m2). Over-inked areas are singled out for display at a touch.
Veripress includes a built-in de-imposition engine, allowing imposed press files to be virtually cut and proofed at published size. Signature groups can be custom built or imported directly from jobs in a number of industry formats such as Dynastrip, Preps and JDF. The user interface features the ability to multi-select individual signatures within a group, allowing mass changes to parameters such as plate offset or page size when working with large publications.
Imposed press sheets can be submitted for proofing with a signature attached. Press operators have the option of viewing an overlaid signature when proofing the sheet or de-imposing press sheets on-the-fly to proof individual pages without the need for reprocessing the original. This functionality saves on both disk storage space and operator search times.
The back page function allows Veripress to virtually back consecutive publication pages onto each other. User-configured paper white point, opacity and back page dot gain are used to accurately simulate the effects of show-through on the current page.
Veripress comes fitted with calibration and verification tools to ensure accurate colour reproduction. The Monitor Calibrator allows for quick calibration of the proofing display using a supported Spectrophotometer.
Veripress includes a system for creating colour verification charts, generated from press ICC profiles or imported from text or CGATS files. Users can define the number of patches making up the chart, process colours, paper and grey balance patch types; and set maximum, average and standard tolerance values for Δe (CIE76, CIE94, CIE2000), ΔH and ΔC. The Calcheck application verifies the colour performance of the monitor directly against the target press standard values and displays the results onscreen. This guarantees a display certified by Veripress is capable of reproducing the full gamut of the target printing process, be it ISO 12647-7, GRACol, a multi-colour or other custom process.
Created to precisely emulate the properties of the press and substrate on screen, press configurations are an integral part of the Veripress softproofing solution. Users define the operating gamut of the press via a match ICC profile. Dot gain curves can be added to compensate for the dot gain of each process CMYK ink and spot colour, as well as that of the platesetter device. Replacement colour sets can be used for printing processes with non-standard ink setups. The printable sheet area of the press can be entered along with its number of ink keys.
Press configurations define the white point of the paper being used. White Point values can be entered manually, extracted from the match ICC profile, or measured from the substrate with a supported Spectrophotometer. The paper’s show-through properties can be defined including a dot gain curve for the back page. Maximum ink weight and horizontal or vertical stretch factor can also be set.
Press configurations can be switched instantly via the touch console to view a job as it would look when printed by a different press, or on another paper type.
