Printing Technology Course

Lesson 1 • Substrates and Their Properties

Examines paper, board, film, fabric, and specialty substrates by weight, coating, and surface texture. Substrate choice directly affects ink adhesion and final print quality.

Lesson 2 • Core Printing Process Categories

Defines relief, intaglio, planographic, screen, and digital processes by their ink-transfer mechanisms. Enables students to classify any press technology encountered in practice.

Lesson 3 • Ink Chemistry and Formulation

Covers pigment, vehicle, and additive roles in ink performance across process types. Understanding chemistry prevents adhesion failures and colour inconsistencies.

Lesson 4 • History and Evolution of Printing

Traces printing from woodblock origins through digital presses, linking historical milestones to modern capabilities. Provides context for understanding why current technologies exist.

Lesson 1 • Colour Separation and Trapping

Explains how artwork is split into process and spot channels and how trapping prevents misregistration gaps. These skills directly reduce press waste and rework.

Lesson 2 • Platemaking Technologies

Covers CTP, direct laser engraving, and screen exposure for creating printing surfaces from digital data. Plate quality determines sharpness, dot gain, and press durability.

Lesson 3 • Imposition and Layout Planning

Teaches sheet and web imposition schemes that maximise substrate use and simplify bindery operations. Proper imposition reduces paper waste and finishing errors.

Lesson 4 • Proofing Methods and Approval

Compares soft, inkjet contract, and press proofs for accuracy and cost. Selecting the right proof type ensures client approval matches final printed output.

Lesson 1 • Colour Control During the Press Run

Uses densitometry and spectrophotometry to maintain consistent ink density and colour throughout a job. Real-time measurement prevents costly reprints and client rejections.

Lesson 2 • Offset Press Components and Functions

Identifies plate, blanket, and impression cylinders, plus inking and dampening systems. Component knowledge is prerequisite to all setup and troubleshooting tasks.

Lesson 3 • Offset Press Troubleshooting

Diagnoses common defects including hickeys, ghosting, setoff, and misregistration using systematic root-cause analysis. Rapid diagnosis minimises downtime and waste.

Lesson 4 • Makeready and Registration

Covers plate mounting, packing, and register mark alignment to achieve tight multicolour registration. Efficient makeready directly reduces substrate waste and setup time.

Lesson 1 • Anilox Roll Technology

Covers cell geometry, line screen, and volume specifications that govern ink metering in flexo. Correct anilox selection is the primary lever for controlling ink film thickness.

Lesson 2 • Flexo Quality and Defect Control

Identifies pinholing, bridging, halo, and washboard defects and links each to specific press or plate variables. Systematic defect analysis reduces waste on high-speed packaging runs.

Lesson 3 • Flexo Ink Systems and Drying

Compares water-based, solvent-based, and UV-curable flexo inks and their drying requirements. Ink system selection must match substrate, end-use, and regulatory requirements.

Lesson 4 • Flexo Plate and Tape Systems

Explains photopolymer plate types, durometer, and mounting tape compressibility and their combined effect on print quality. Plate-tape interaction controls dot gain and impression.

Lesson 1 • RIP Software and Colour Management

Covers raster image processing, ICC profile application, and linearisation for accurate digital colour output. RIP configuration bridges design intent and physical press output.

Lesson 2 • Wide-Format and Specialty Inkjet

Addresses grand-format flatbed, roll-to-roll, and hybrid inkjet systems for signage, decor, and industrial applications. Substrate preparation and ink curing are critical for durability.

Lesson 3 • Variable Data Printing Workflows

Designs database-driven print jobs that personalise text, images, and barcodes across large runs. Variable data printing maximises relevance and response rates for print buyers.

Lesson 4 • Inkjet Printhead Technologies

Compares piezoelectric, thermal, and continuous inkjet drop-formation methods and their print-quality implications. Printhead type determines substrate compatibility and resolution capability.

Lesson 1 • ICC Profile Creation and Application

Builds device profiles for scanners, displays, and presses using characterisation targets and profiling software. Profiles translate colour data accurately between devices in a managed workflow.

Lesson 2 • Colour Measurement Instruments

Covers densitometers, spectrophotometers, and colorimeters, including calibration and measurement geometry. Accurate measurement is the foundation of any objective quality system.

Lesson 3 • Statistical Process Control for Print

Uses control charts, Cpk analysis, and run charts to monitor and stabilise press colour and register. SPC converts reactive quality checks into proactive process management.

Lesson 4 • Quality Management Systems in Print

Integrates inspection plans, nonconformance reporting, and continuous improvement cycles into print operations. A formal quality system reduces defect rates and builds customer confidence.

Lesson 1 • Specialty Decorating Processes

Introduces hot stamping, embossing, thermography, and UV spot coating as value-added print enhancements. These processes increase perceived quality and product differentiation.

Lesson 2 • Screen Printing Ink Systems

Compares plastisol, water-based, discharge, and specialty inks for garment and industrial screen printing. Ink selection determines hand feel, durability, and curing requirements.

Lesson 3 • Pad Printing for Irregular Surfaces

Describes cliche plate etching, silicone pad selection, and ink transfer for printing on curved and textured objects. Pad printing is the primary method for decorating promotional and industrial parts.

Lesson 4 • Screen Printing Fundamentals

Covers mesh selection, emulsion coating, exposure, and squeegee technique for consistent ink deposit. Screen printing delivers heavy ink films and opaque colours unmatched by other processes.

Lesson 1 • Binding Methods and Selection

Compares saddle stitch, perfect bind, case bind, and spiral binding by durability, page count, and cost. Binding method selection must align with product use and budget constraints.

Lesson 2 • Lamination and Coating Processes

Explains thermal lamination, aqueous coating, UV coating, and soft-touch finishes for protection and aesthetics. Coating selection affects tactile quality, durability, and downstream printability.

Lesson 3 • Cutting and Folding Operations

Covers guillotine cutter setup, fold types, and scoring for accurate, crease-free finishing. Precise cutting and folding are prerequisites for all subsequent bindery operations.

Lesson 4 • Die Cutting and Embellishment

Covers flatbed and rotary die cutting, foil stamping, and embossing for packaging and promotional products. Die-cut accuracy determines structural integrity and visual impact of finished pieces.
