pressSIGN-Pro V8 main features
- Dynamic Density Adjustment(DDA) uniquely predicts best possible density based on the selected print target and the actual paper, ink, chemistry in use for that job
- Auto target adjustment for substrate – user doesn’t need to create a multitude of press targets for each substrate to get best quality of print.
- Creates and updates tonal curves using either TVI (dot gain) or patent pending 4CX technology (grey balance).
- Scores the measurement against the print target giving a colour coded overall score and a score for each of the measured criteria. Print targets with tolerances and scoring are fully customisable
- Print targets – all international standards supported. Print targets fully customisable
- Spot Colours – includes Pantone® libraries for up to 16 colour printing, create custom spot libraries
- Use any colour bar
- Trend analysis reports showing press, operator, shift performance and wastage of print process for single or multiple jobs
- Monitor performance from the production office or from anywhere connected to the internet
- Soft Proof at the press or in the production office, see the impact of paper colour and the actual press measurements on the job
- Check consistency across the press and against the OK sheet
- Connects to all scanning spectrophotometers and many third-party closed loop systems
pressSIGN’s Dynamic Density Adjustment ensures that the operator is always achieving the closest colour match to the press target whatever the ink, paper or press environment. On each new job pressSIGN recalculates the correct density adjustment based on the current conditions. In fact, pressSIGN only needs to read one patch to know how to adjust the density.
The pressSIGN-Pro client shows the operator how to adjust each ink key across the press. The operator is targeting 0% adjustment, which means that if the ink level is either increased or decreased then the Delta E will rise. Instead of trying to hit an arbitrary density target the operator is achieving the best possible colour match to the press target.
Optionally ink zones can be turned off as part of the measurement and scoring functions when, for example, there is no significant coverage.
Auto Substrate adjustment
Printers who are asked to print to international printing standards like ISO 12647-2 or GRACol will often be asked to produce work on paper stocks that deviate from the standard. pressSIGN v 5 gives print buyers and printers the option of allowing pressSIGN to automatically amend the print target based on the substrate’s white point.
Changing the white point target in response to paper color gives a better visual representation of the original.
Set and update tonal curves
pressSIGN offers two methods of creating tonal curve adjustments, Tonal Value Increase (TVI) and patent pending 4CX. By measuring the colour bar containing a minimum of three tonal patches per colour (e.g. 25%, 50% and 75%) pressSIGN creates tonal adjustment curves and exports these curves to a whole variety of RIP formats for platesetters and digital devices.
Alternatively output the tonal curves to AutoCurves and apply the adjustments to a PDF workflow. AutoCurves is an additional application that is useful in a digital environment or where a platesetter RIP is unable to update an existing curve.
TVI, usually deferred to as dot gain, is the traditional way that printers have matched international standards such as ISO 12647-2. It is a simple method of achieving colour matching to the standard.
Patent pending 4CX (4 Colour Exchange) technology targets grey balance for the tonal adjustments. 4CX takes into account black and white points of the target and print to produce the best visual match. For more details on 4CX technology visit the dedicated web page.
When all conditions including ink and paper are ideal on a sheet fed offset press then 4CX and TVI adjustments will produce the same results. However, we recommend 4CX on non-offset devices and where ink and paper do not precisely match the ISO standards.
Each measurement is scored
Every measurement is given a score and colour coded to make it easy to decide how well that sheet was printed. The sheet is given an overall score which is further broken down into different measurement criteria. Finally the production report gives a score for all the measurements in the job.
The job criteria measured and scored are
- Primary colours
- Spot colours
- Grey Balance
- Overprints – Lab and Trapping
- Sheet consistency
- Consistency against an OK or accepted sheet
- Paper colour
pressSIGN supports all international print standards:-
- ISO 12647-2
- ISO 12647-3
- ISO 12647-4
- ISO 12647-6
- ISO 15339
- Japan Color
Create customized print standards based on CMYK ICC profiles. pressSIGN also allows you to select a profile for the print condition and a separate profile for the grey balance. For example, the customer might require a job to be printed on uncoated paper but have supplied the file with a coated profile like ISOCoatedv2.icc. The ability to set a different target for the grey balance to the print condition allows you to generate correction curves that produce the best possible visual match.
Utilising an ICC profile as the print target allows pressSIGN to adjust the print target according to the colour of the substrate. Printing to the amended target will produce a better visual match to the proof. Export the amended ICC profile to pre-press for proofing or soft proofing.
Create a print standard based on a single or set of previously measured printed sheets. It is useful to capture the existing print set up so that it can be replicated for re-runs.
To ensure brand consistency spot color printing is essential. pressSIGN-Pro can measure and control from one to 16 colors. The spot colors can be selected from either the Pantone® libraries or customer created libraries. Custom color libraries can be exported to other users.
The Pantone® spot colour libraries are included within pressSIGN. Select any Pantone colour and pressSIGN will show the operator how to adjust the density to achieve the best possible match on the substrate.
Create custom spot colour libraries by measuring the colours, importing colour data files like CxF, or type in Lab values.
Compare any measurement with the nearest colour from the spot colour libraries.
Why rely on a visual judgements from a faded book when all can benefit from centrally controlled spectral data.
Any Colour Bar
Create any colour bar in pressSIGN’s colour bar generator and pressSIGN will score the reading against the target you have set.
Import CGATs or CxF data files and make these the print target files. pressSIGN version 5 gives the user huge flexibility to determine what will be measured. For example, make the target bar a single colour with multiple tint patches to see how the printing device is producing a tonal curve for that colour. Check on the across the sheet consistency of a digital printer.
Create or import multi-line color bars such as the GRACol P2P target or FOGRA/UGRA Media wedge or simply copy an existing color bar including slurs marks.
pressSIGN-Pro offers the production manager much better understanding about the performance of the printing devices and the operators under his control through pressSIGN’s production reports. See which operators take longest to get to production. pressSIGN-Pro provides production managers with detailed analysis reports for individual jobs and across multiple jobs. Compare the performance of
- digital printing devices
- consumables and paper.
Produce a certification report for clients to demonstrate the quality of print.
pressSIGN-Pro also produces measurement report and a scoring report to give production manager’s a quick overview of any particular job.
pressSIGN v 5 is a SQL Server based product that allows multiple clients to input and monitor the data from the printing devices connected to it. As part of the basic configuration pressSIGN-Pro v 5 is shipped with three clients additional clients can be added as required.
- the Pro client that is used by the operator to measure and control the print device
- the Trends client for use in the production/pre-press office – to assign jobs to the operator, to update tonal curves, to analyse performance and communicate to customers and colleagues. Has the same functionality as the Pro client without the ability to read in new data.
- the Mobile client for the production manager to monitor performance and communicate with the operator from anywhere connected to the internet
While the Pro client sits by the printing device in order to read and monitor individual printed sheets and show the operator how to make the necessary adjustments to the press, the Trends and Mobile clients allow pre-press and production managers to monitor the press performance without the need to be on the shop floor.
The pre-press manager can see all jobs that are currently printing from the office, new jobs can be created, targets created and jobs assigned to the right press and the right operator. When the operator signs into pressSIGN he only sees his own jobs. From the pre-press office, the manager can update tonal curves without the need to visit the factory floor or disturb the operator. All production reports and analysis can take place using the pressSIGN-Trends client.
Keep in touch with the performance of the operators and presses from anywhere connected to the internet with the pressSIGN-Mobile client. Send and receive chat messages directly with the operator.
Soft proofing is included free of charge with pressSIGN-Pro. All pressSIGN-Pro and Trends clients have the soft-proofing module built-in.
Use the soft proofing module even before printing has started. Open up the print job in pressSIGN and measure the actual paper colour. See the impact the underlying substrate is going to have when you print.
Use pressSIGN’s soft proof module at press side to compare the printed sheets with the target. Use the soft proof module in the production office to see how well the job is being printed. See the impact of updating the tonal curves on the printed sheet.
Check for all types of consistency
Consistency is vital for all quality conscious print buyers. Consistency between printed jobs, wherever they are printed, consistency throughout the job and consistency across the printed sheet are all vital in matching clients requirements. presSIGN-Pro tracks these issues on behalf of the quality control or brand manager. At the same time pressSIGN-Pro shows the operators how to achieve this consistency.
