Sustainability of Liquids with Inkjet Technology Daniel J. Fry February 25, 2008
Definition of Sustainability • According to Webster – of, relating to, or being a method of harvesting or using a resource so that the resource is not depleted or permanently damaged • According to Wikipedia – is a characteristic of a process or state that can be maintained at a certain level indefinitely.
Concerns of the Trade Shop • Film image setters are becoming harder to find and more difficult to maintain and repair • Silver film is getting expensive, the longer term viability is unknown • Lost margins from converting liquid plate production to digital sheet production
Options Available to the Trade Shop • Remain on Silver Films – Acquire backup processor or processor parts – Secure long term supply agreements with the film suppliers • Go Digital – High cost of entry – Higher raw material costs • Identify alternative options for film supply
Silver Film Alternatives Thermal films • Slow, low quality, film does not store well Ablative film • A digital image setter is required Ink jet film systems • Proven technology in the Screen Printing market since 1996 • Cost neutral position to silver film • No processor effluent or silver recovery issues
Aspect Quadra Systems • Introduced in 1996 to the Screenprint market and currently there are over 600 systems installed • Aspect Quadra is a Proven reliable and inexpensive “all-format” turnkey system • Printer, film, hardware, and ink are designed for best results of a commercial user • Established regional technical support system already in place Aspect Thermal System 1996
Aspect Quadra Advantages - Flexo Customers • Proven high quality commercial grade printer • Film & ink cost are comparible to silver film • In house control of production schedules • Interactive layouts for job “nesting” • Scalable system, ability up to 4 printers to the RIP for increased productivity • Waterproof, durable instant dry film • Color Halftone Simulation Proofs option
Aspect Quadra System Details • Roland Pro-II commercial printers • Film widths 16” to 65. 75” on 100 ft. rolls • High density Quadra-K waterbased dye ink • Wasatch RIP Software for quality process color screening • Custom-built Windows XP workstation and 17” LCD monitor
Roland Pro-II Printers Roland Pro-II FJ-540 54” width, Piezo printheads Film take-up reel (optional) Roland Pro-II SJ-645 64” width, Piezo print heads Film take-up reel (optional)
Wasatch RIP Software • Wasatch Soft. RIP is used for all Quadra systems - partner since 1995 • Wasatch version provides vital features – – Monochrome drivers for film output Ink volume/droplet control Special precision rosette screening Layout features for film savings • • Auto-nesting Manual nesting Cropping/rotation Distortion scaling – Pre Linearized configurations to 85 line – Color Halftone Proofing profiles to 85 line • Ability to print on boards up to 4 mm thick (e-flute)
Quadra-K Ink • Dye black, water-based ink provides – Maximum film penetration – Excellent halftone dot formation – Bulk ink options, available in cartridges, liters, gallons • Color ink available – – – Cyan Yellow Magenta Light Cyan Light Magenta
Quadra Inkjet Film • • 1 - Anti-static back coating and traction enhancer 2 - Primer coat 3 - Polyester base material 4 - Primer coat 5 - Blocking layer and seal to prevent spreading 6 - Absorption layer and microencapsulation 7 - Topcoat-receiving layer with matte particles -7 -6 -5 -4 -3 -2 -1 Quadra micro encapsulation film - cross section
Quadra film attributes • Quadra film is designed for quality line and dot images • High density = 3. 5 to 4. 0+ U. V. • Instant dry via total encapsulation (dye ink) • Totally waterproof (submersible) • Anti static traction back coat, eliminates droplet deflection • 100 foot rolls maintain register accuracy • Dimensionally stabilized for excellent registration properties
Finished Film • 75 lpi, round dot – Output on a Roland FJ 540 using 1440 dpi output • Compatible with typical film cleaners 10% dot 70% dot
System Productivity • Quadra Output Speeds • As with all output devices slower = higher quality/resolution faster = more throughput for less critical jobs • Quadra speed is adjustable to meet requirements
Customer Output Times • Times listed below are to produce a 40” x 40” film Output Setting (dpi) Time (minutes) 720 7 min 20 sec 1080 10 1440 15
Aspect Quadra Specifications • Registration – start to finish accuracy and fit between films – 0. 014” over 8 feet Factors that affect registration • Film loading - tensioning • Weight of roll (100 foot rolls) • Cleanliness of printer media deck and pinch rollers • Skew - the ability to produce geometrically square output – 0. 039” or less over 4 feet - grid test Factors that affect skew • Film loading and initial calibration • Mechanical accuracy of printer • Tension in media 120” 5 color job
Summary • Aspect Quadra System offers the Trade Shop the following benefits: • Proven commercial technology • Durable, archivable film in widths up to 65. 75” • Cost effective replacement to silver films • A means to keep Liquid plate manufacturing sustainable
