High quality offset and digital printing

We ensure control and quality.

Continuous checks and calibrations are performed on all systems to ensure optimum repeatability of printed material. We provide colour profile reports and quality certifications for each printed product. We comply with ISO 12647-2.

What are the factors for choosing the printing method?

For small print runs, we use digital printing; for medium/high and large print runs, we use offset printing, for efficiency and convenience. The cost of offset printing is inversely proportional to the number of printed copies, since it includes a pre-press process and therefore a fixed cost for starting.
On the other hand, digital printing has an unvaried cost for a single copy, being therefore the most convenient choice for small print runs.
Offset printing takes longer than digital printing because the set-up and adjustment times of the machine are more complex.

Digital printing presses use direct printing technology: text, graphics and images are transferred directly from the computer to the paper without going through the offset plate. Currently there are two main digital printing methods: xerographic and inkjet.

SAB digital machines :
Digital inkjet machine Epson Plotter 106 cm light 5 colours.
Konica Minolta 4-colour digital xerographic machine f.to SA/3.
Kodak 5 colour digital printing press with in-line painting. Possibility to use LightBlack HD dry ink for very fine details and skin homogeneity. F.up to 35X90 cm.

The offset system has an non-direct printing mode: three contact cylinders transfer the image from the offset plate to the blanket cylinder and from the blanket cylinder to the paper through the pressure cylinder.

The SAB offset press fleet covers all working areas from 1 to 5 colours in formats up to 72X103 with production yields of up to 15,000 cp/h.
SAB has chosen KOMORI for 30 years.
SAB offset machines :
directly connected to the pre-press department via the CIP3 interface for ink-profile management.
- in-line with the X-rite spectrodensitometer which scans the colour control bars on the printed sheets, transmitting density measurements and L*a*b spectrum data for colour retention throughout the run.

L*a*b or CIElab is the colorimetric model defined by the International Commission on Illumination, the colour is identified by three values: L luminance, expressed in percentage (0 for blacks and 100 for whites), a and b, which are two ranges of colours going respectively from green to red and from blue to yellow, with values going from -120 to +120).
