pressSIGN 3 - full press width color bar
Generate a color bar for the full width of the press sheet (see screen shot)) or as a single set of patches for placement on the press sheet. Use the full width color bar to replace your current color bar or use the single color bar as an additional bar on the sheet. See pressSIGN-Pro for details on how to adjust each ink-key.

pressSIGN generates the color bar based on the press target you have chosen. For example, you may have selected an ICC profile as your press target but your customer wants to print on a different paper color. Read the new paper color with the Eye-One, re-calculate the grey balance, select the measure points for the tints and save the settings. Now generate a new color bar based on your customers needs.

pressSIGN 3 predicts the correct density
All international printing standards set target L*a*b* color values for the primaries (CMYK). pressSIGN converts these target colors into density settings that the press operator can use. See the pressSIGN main window above where pressSIGN tells the operator that for the best results the magenta density needs to be increased by 5% , the yellow density needs 2% more but the cyan and black are as close to the standard as that ink, paper and press combination will allow.

pressSIGN has generated ideal target densities for this press sheet. These densities need to be applied across the width of the press sheet by the operator.

For a more sophisticated report see pressSIGN-Pro which tells the operator how to adjust the density of every ink key across the press to meet the L*a*b* value targets.

pressSIGN 3 adjust the plate curve.
To match the customer's proof or meet any ISO 12647 standard the dot gain on press must be controlled. pressSIGN reads the dot gain from the color bar and generates an adjustment curve. This plate adjustment curve is then exported to the plate or imagesetter RIP. Average several readings to get a smooth curve. Import readings from another press to create average plate adjustment curve to apply to two or more presses.

pressSIGN 3 compensates for dry-back
Use pressSIGN both to evaluate the press sheets and adjust the press during the press run. Because pressSIGN compensates for any color shift that occurs as the ink dries, use pressSIGN to adjust the press-on-the-fly. Adjust the densities as suggested by pressSIGN and find the colours will dry back to hit the required targets. Each control strip reading takes only a few seconds and you have a objective measure of the colour, grey balance, trapping and overprint.

Measure the control strip in one sweep or individual patches

pressSIGN step by step guide to accurate printing

pressSIGN takes you quickly and easily to your own or international printing standards. pressSIGN's five easy steps reduces make-ready times and improves your colour. pressSIGN's tools allow you to test the quality of the printing throughout the run and to make any density adjustments knowing any colour shift during ink drying will be compensated for.

Measure & compare dot gain for process and spot color

Complete set of measurements in seconds
pressSIGN works in conjunction with the X-Rite Eye-One spectrophotometer and reads the pressSIGN control strip in seconds. Choose the control strip to suit the job or press. Read a strip that runs right across the press sheet up to B1/1000 mm wide (with the Bodoni extended ruler) or place a single set 23 patches anywhere on the press sheet. Read either the strip with one swipe . Alternatively measure the patches individually. When you have read the strip you'll receive an instant report on all aspects of the press sheet (see the main window above).The speed with which pressSIGN operates allows you to monitor your press run constantly. You can therefore ensure the complete run conforms to the standard selected

Choose the right press target
Select different international printing standards according to the type of press you are running, the type of paper, the appropriate dot gain curve and your customers needs.

Select the standard or create your own

All standards include the choice of appropriate paper types:

• ISO 12647-2 for sheet and web offset
• ISO 12647-3 for newsprint
• ISO12647-4 for gravure
• ISO 12647-6 for flexographic
• GRACol 2006 (G7)
• Already measured press sheet: - Capture the way the press is printing now so that you can reproduce the same condition when you need to re-run the job. Ideal for reproducing work that is outside any standard or for customers who want to conduct a press pass.
• CMYK ICC Profile - import a profile and then adjust the profile see below
• Custom target - type in the target L*a*b values for the primary colors (CMYK) plus the dot gain etc.

Import an ICC Profile as your press target

It is often easier to match press and proof using a common ICC profile. An ICC profile is used throughout the pre-press workflow and for color accuracy it is often better to use the same profile as the press target. presssIGN makes matching the ICC profile easy but also adds further features to help color matching on press.

• Import any CMYK ICC profile
• Measure or type in the paper color that will be used to print the job. This will adjust the Lab value targets of the primaries and amend the dot gain. You can then re-calculate the grey balance.
• Export the adjsuted ICC profile back out of pressSIGN for use in the pre-press workflow.
• Save this new standard and then generate a new color bar to match the new target.

Import an ICC profile, with options to change paper color & grey balance

Use the current readings as a new standard

Some print buyers still want to be at the factory in order to pass the job on press. pressSIGN allows you to capture how the job as it is printed, so that it can be replicated for the rest of the run and for any re-runs.

Just read the press sheets as they come off the press. Select the readings that pass the print buyers standards and average those readings in pressSIGN. Save these average readings as a new standard. You can then return to this saved standard at any time and reproduce the job exactly.

pressSIGN also allows you to customise a standard by typing in target values for the primaries and dot gain etc.

Compare colours, density and CIELAB Delta E anywhere on the sheet

Once the standard has been set select the default tolerances or adjust the tolerances to suit. For example you can add or remove tolerances for grey balance, overprint and trapping.

pressSIGN turns the Eye-One into complete press measurement tool.
Measure the Lab value, density and dot area and compare it with other readings either from the press sheet or your Pantone book, a proof or ink drawn down. Set pressSIGN to automatically check the DeltaE or Dot Area of the CMYK primaries or compare the Lab values/Dot area of secondary colours or spot colours. You can even type in a target Lab value from Adobe PhotoShop, and compare this with the colour on the press sheet.

pressSIGN 3 - Database design
Every pressSIGN 3 reading is stored in the pressSIGN database. Search, sort and select jobs by

• Job name
• Client
• Press
• Operator
• Comment
• Date
• Time
• Standard
• Score

The pressSIGN database design helps production managers understand the performance of their press(es). For example, select jobs by the press or operator and review the score for all the jobs printed on any day or shift. Searching the database for previously entered comments helps identify performance changes due to alterations in consumable use. Save searches for repeated use.

pressSIGN traffic light system
Each reading in pressSIGN is given a score. Select multiple readings for an average score. pressSIGN comes with a default scoring system but users can adjust the scoring to suit their needs. The default percentage for an acceptable print (solid green) is 80%, the production controller can set this percentage to any value required. The other scores will be adjusted to compensate.

pressSIGN is used wherever people care about print quality, from largest printers to two-man businesses, in over 40 countries around the world.
