Screening technology Screening technology for the futurefor the future
A new screening technology must fulfil 2 basic demands:
1. It must be better than the screens used hitherto• better with respect to the quality of the final product• better in its operational application
2. It must avoid problems and irregularities • without additional cost or workload• without risk of reductions in quality
SandyScreen products 2
Challenges of the future
• qualified to be applied in all types of offset printing• easy integration into existing production processes• operational on all current platesetters and presses• stable quality even in high circulations• no loss of data – all details in light and shadow appear in print• screen frequency to be selected and adapted to the product• no shifts in tonal value• repeatability of plates in identical quality• no disturbing screen structures as moiré, rosettes etc• printing element not visible• easy handling by prepress and printing crews

Advantages of SandyProfessional against other screening types( round, elliptic, chaindot , FM , Hybrid etc.)
• No abrupt screen transitions - optimal highlight details
• Higher screening frequencies possible
• Perfectly controllable at all levels of grey balance
• Reduction of technical disturbances such as moirés etc
SandyProfessional rises your products to a new quality level !

SandyProfessional Scope of applicationScope of application
15
SandyProfessional integrates easily into existing production processes.
• can be installed on Harlequin based RIP‘s (others to be evaluated)
• can be imaged without problems on current platesetters
(Autologic, Punch, Graphix, Newsetter, Polaris , Krause, Lüscher etc.).
• stands perfectly clear on all plates (Kodak Polychrome, Fuji, Agfa etc.) and permits to repeat reproductions in identical quality.
• produces outstanding images and a stable quality on current presses (manroland, Wifag, KBA , Goss etc.)
• in-house standards (IFRA/ISO) can be maintained or re-defined
• once on paper, is elegant and smooth like silk.
SandyScreen products
SandyProfessional Technological advantages
16
• The dot increase can be calculated, controlled and steered precisely
• Gradation curves on the RIP guarantee optimal and flawless reproductions
• Printing elements no longer visible – no more annoying screen structures (moirés, mechanical breaks) in pictures
• Dot closure no longer a problem
• Easy to use for prepress crews, thus efficient and economic
• Specially designed for CtP and CtcP
SandyScreen products
SandyProfessional Operational advantages
17
• Existing installations (platesetting equipment, printing presses etc.) can be used unchanged
• Customers‘ demands can be fulfilled more easily.
• Selected commercial markets become accessible
• High quality demands in sheetfed and web print can be met
• Increased profitability due to increased productivity
• Reduced waste of time and paper
• Leading market position – higher competitiveness
• SandyScreen is independent. No obligation to engage in a package deal or longterm commitment
SandyScreen products
SandyProfessional Commercial advantages
• „A project team comprising in-house and SandyScreen experts succeeded in significantly improving the quality of black/white and 4colour images“
• „Since introducing SandyProfessional the number of subscribers has increased and advertising agencies hold the product in high esteem. We have also noted a complaint rate of virtually zero“
• „There was no need to modify existing machinery“
• „Advertisements are now reproduced with excellent, brilliant quality and editorial reproductions exhibit no visible screen elements or other distractions, such as moiré effects, rosettes...“
• „Going into Selected Commercial Printing, SandyP would lead to a greater utilization of the equipment and better revenues though the opportunity to print magazines, brochures etc.“
