SandyScreen offers the following products qualified to achieve an optimum quality in offset printing

• the revolutionary new universal printing element SandyStar
• SandyProfessional developed for newspaper printing
• the optimisation program "Tintorello"

SandyScreen screening technologies contain all required criteria for the production of top quality products and offer the following specific advantages:

• no dot closure up to 99%.
• no more disturbing moirés and mechanical breaks.
• no annoying screen structures and visible dots.
• original data supplied appear fully in print thus guaranteeing optimal and true reproduction.
• the plate repeatability is x-times absolutely identical and shows no shifts in tonal value.
• the dot increase can be calculated, supervised and controlled.

Additional general advantages of SandyScreen`s screen products:

• integrate easily in existing workflow and production processes.
• can be installed without any problems in most current Harlequin and Harlequin-based RIPs.
• permit easy handling on all current plate-setters (Autologic, basysprint, Newssetter, Polaris etc.).
• on current presses they ensure a most reliable stability even in high circulation.
• in-house printing standards (ISO/IFRA) can be maintained or re-defined transparent and easy to handle in the printing process.
• the screen frequency can be adapted to the product depending on plate and paper type.
• easy to handle by prepress and printing staff.
• no additional or new investments or modification of existing equipments required SandyScreen is neutral and independent

SandyStar: the new quality-modulated QM screen for the future

SandyStar is a new and universal quality-modulated printing element for all types of print, from newsprint to job printing. It was recently developed by SandyScreen and has since proven its viability in newspaper production with excellent results.

The revolutionary new technical application options of QM screen SandyStar:

The special SandyStar QM-technology is designed to achieve double the screen frequency selected in the RIP without needing to increase the plate exposure time.

• 24L/cm produziert 48L/cm (61L/inch = 122L/inch)
• 30L/cm produziert 60L/cm (90L/inch = 150L/inch)
• 40L/cm produziert 80L/cm (100L/inch = 203L/inch)
• 60L/cm produziert 120L/cm (152L/inch = 304L/inch) usw.

Despite the double screen fineness, the exposure time remains constant.

Identical repeatability of the plate is ensured.Through the option of calculating and managing the dot inserts and the dot closure, the respectively best suitable RIP gradation curve can be allocated to the machine characteristics, taking into account all criteria such as paper structures, colour, etc.

The increase of tonal value in:

• newspaper rotations, including water-free ones!
• job roller offset machines.
• sheet offset machines

is also taken into account in the parameter calculation when installing gradation curves in the RIP.

With SandyStar all screen percentages of 1-99% can be calculated in a targeted and precise manner in accordance with the respective strengths and weaknesses of the printing technique used and ideally adapted to the existing circumstances.

Due to the fact that the individual screen cells are always freestanding, this quality-modulated screen technology also ensures better moisture drainage in the job roller area during printing. (Reduction of paper waves and passer problems)

In newspaper production, SandyStar works with the standard of 1270 dpi and can be used up to a screen frequency of 203L/inch (80 L/cm) (see paper types below), provided that the exposure unit and the plate type used are suitable for this! 133L/inch (52L/cm) and 152L/inch (60L/cm) are intended for normal newsprint papers, 203L/inch (80L/cm) for UPM enhanced white papers.

With 2540 dpi resolution, on the other hand, you can easily work with 203/254/304L/inch (80/100/120L/cm), depending on exposure unit and plate layer here too.

With photopolymer plates, only a screen fineness of 102L/inch (48L/cm) is possible.

SandyStar is particularly suited for RIPs based on Harlequin. Other RIP products on request!

SandyStar is an innovation that can create new quality in printing!

The printing element SandyProfessional for newspapers

SandyScreen`s printing element (screen dot) SandyProfessional replaces the traditional AM screens still used and offers advantages against hybrid and FM screening methods.

It improves the printing and image quality noticeably. The screen retreats into the background and is no longer disturbing due to its finer resolution.

SandyProfessional is applicable to web and sheet-fed printing. The existing printing techniques and installations need not be changed.

The screen frequency can be adapted to the product in a range of 122-152L/inch or even higher in special cases. Internal printing standards can be maintained or re-defined (IFRA/ISO).

SandyProfessional has been specially designed for CtP and CtcP.

The TINTORELLO Quality program

aims at maximising the newspaper product within the existing process environment over the entire workflow.

TINTORELLO Quality concentrates on 4 elements:

• Analysis + Evaluation.
• Prepress Optimisation.
• Implementation of SandyScreen technology.
• Sustainable quality management.

TINTORELLO Quality:

• analyses actual parameters.
• defines optimization potentials and requirements.
• elaborates proposals and project programs.
• Installs the SandyScreen printing elements in line with the characteristics of output equipment (CtP, Plate, Press and consumables)
• customizes Sandy screens via RIP gradation curves.
• develops in-house quality standards (ISO 12467-3).
• defines standard operating procedures (SOP).
• establishes a quality assurance system.
• performs process oriented instruction and qualifications offers prepress training and cross skilling of operators
• generates overall quality awareness.
