Educational and technical training activities are addressed to packaging printers (flexible packaging, labels and corrugated), platemaking companies, repro studios and graphic designers, manufacturers and distributors of printing presses and related technologies, graphic schools and trade associations, brand owners.
Program of activities is customisable and covers the following topics:
- Flexography within printing systems for packaging
Printing systems for packaging; printing formes and ink restraints; ink transfer in different printing systems; positioning flexography; history and development of flexography.
- Components of the printing group
Anilox: cells and structures, types and development of anilox rolls, cell geometry and volume, ratio plate:anilox, suggested volumes, inventory and maintenance.
Ink metering: doctor blade, ink chambers and ink flow.
Inks: types and composition, pigments, resins, solvents, viscosity, formulation.
Plate: relief, thickness, hardness, surface geometry, digital plates and flat top, measurements.
Cylinders and Sleeves: structures, printing repeat, undercut and plate package compression.
Plate mounting: adhesive tapes, structure and components, cushion tapes, printing impressions.
Substrates: segmentation of substrates, characteristics and applications, surface tension and printability, surface properties.
- Color, measurements and prepress
Understanding color: light and human vision, additive and subtractive synthesis, color models, densitometry, spectrophotometry, DeltaE.
Reproduction: principles of graphic reproduction and tonal value reproduction throughout the workflow.
Color management: gamuts and output devices, color profiles, color conversion, printing conditions.
Design: players and roles, design basics, color proofs, guidelines text, lines, trap, line screen, barcodes.
Prepress: workflow, understanding and managing output intents, ISO/TS 10128 (TVI / grey balance / repurposing), spot colors, expanded gamut, plate distortion.
Platemaking technologies, conventional and digital plates, polymerisation process, platemaking calibration (exposures and processing), tonal values reproduction, solutions for flat-top, CtP calibration, direct engraving.
- Calibration and process control
Quality: understanding system variables, packaging that sells, contrast and print quality, approaching process calibration.
Calibration: consistency, repeatability, predictability; using statistical control.
Optimisation: scope and methods of optimisation, variables involved, ink laydown, compensation curves, highlights, primary color values.
Fingerprint: definition of printing condition and procedure, elements of control testform, calibrating in grey balance (G7), statistical control.
Characterisation: procedure and test form, common mistakes, managing characterisation data.
