Anderson The WireJet can print with Acrylic Toners. We use Acrylic Toners with our underpainting services. Acrylic Toners are concentrated pure artist pigment with just a little bit of acrylic added to “temporarily glue” the pigment to the canvas. The colors are pure, rich and saturated. Dye based ink jet inks fade with sunlight and don’t last like artist pigments. This requires the artist to opaquely cover every little bit of the canvas or white spots appear in the painting years later as the sun fades the ink in thinly painted areas. The extremely small pigment particles of light-fast, "permanent", inkjet inks can migrate through successive layers of dried paint and come to the surface of the painting years later. This is similar to what happens with ball point pen inks or marking pen inks that migrate to the surface of a painting. Unfortunately, the painting can’t simply be placed in the sun to bleach out this type of permanent inkjet ink! When ink jet inks are printed on actual artist canvas, much of the ink is absorbed into gesso and leaves only a trace image. The gesso acts like a sponge! Giclee’ is inkjet printed on a canvas which has been given an additional coating to keep the ink jet inks from being absorbed into the porous gesso. However, paint needs the porous gesso to stick! Oil paints especially stick very mechanically. Paint is like sod...it grows roots. Put paint on top of a giclee ... and the paint can peel off!!! There is no structural integrity! The Acrylic Toners allow you to add acrylic paints, oil paints, oil pastels, or colored pencils. The acrylic toners have large pigment particles. The toners want to mix into any medium that is applied on top of them. They are designed to have a great affinity to liquid mediums. Think of them as dehydrated paint. The toners need alkyd or acrylic medium to be brushed on top to permanently glue them to the canvas. When the WireJet is used with Acrylic toners, the artist can take off in any direction he chooses: oils, acrylics, pastels, or pencil! You decide or use them all. Inkjet can be used safely by artists in special situations. The ink used in the inkjet must be UV-sensitive, dye based, type of ink. If and when the dye comes to the surface of the painting, the sun can be used to bleach out the ink. Only dye based inks printed directly on the canvas gesso are acceptable. The artist must insure that he thoroughly covers every bit of the canvas with opaque paints. If not, white spots will appear on the canvas years later. Finally, the ink jet printing should only be done directly on the gesso surface. DO NOT PAINT ON GICLEE' CANVAS. The coating of the giclee' canvas will prevent permanent bonding of the paint to the canvas!   Theory of Operation: The WireJet 2- A wire is used to bring ink or paint from a reservoir to an air jet stream where it is carried to a print surface. The wire is controlled so that the speed of its advance through the air jet stream meters the quantity of paint injected into the air jet stream. The wire begins immersed in a paint reservoir. As the wire is pulled from the reservoir, a coating of paint on the wire clings to the wire. The amount of paint clinging is controlled by a scraper riding next to the wire as it is advanced. The wire with the paint coating is then drawn close to an air jet. As the paint on the wire reaches the jet of air it is pulled off the wire and enters the air jet stream. The paint in the air jet stream impinges on the printing surface. A stepper motor is used to draw the paint coated wire through the air jet. Your computer is used to control the advance of the stepper motor. This "WireJet" injector is swept across a surface to be painted to create the final image on the printed surface. The unique advantage of the WireJet is that it is not limited by paint particle size or large particle contamination. The device is relatively insensitive to the physical properties of the paint. The device can use paint pigments already designed for the sign and art industries.   Resolution and Speed: Painting speed can be increased at a cost of reduced image quality. Several variables are adjusted together to yield maximum quality for a given painting speed. Each of the variables is discussed separately and a recommended starting setup is given. The single variable affecting painting speed more than any other is the line spacing set by you on the main menu in the software (see the Main Menu - Help). The velocity of the print head across the media is usually already adjusted for maximum performance. The only way to push painting speed further is to increase the line spacing which thereby reduces the total number of lines in the painting. To increase line spacing, other variables such as scraper thickness, separation between print head and media, percentage of paint printed in the Color Control Panel, and air pressure must also be adjusted. The scraper thickness determines the quantity of paint per injection. Increased paint injection volume will enable greater line separation, greater separation between the paint head and the media, and will result in faster print speed and reduced image quality. Increasing the scraper thickness by .001" will cause a noticeable increase in paint volume per injection. Scrapers from Pixation are nominally 0.009". With increased scraper thickness and subsequent increases in paint injection volume the distance between the paint head and the media must be increased to allow for greater line spacing and therefore faster print speeds. However, increasing the separation between the paint head and the media causes more blending of paint injections and decreases image sharpness. A change of .050" will cause a noticeable change. Moving the print head too close to the media will cause insufficient blending so that the individual paint injections will appear as small round dots. Insufficient separation will also cause paint lines to appear distinct. Increasing the air pressure pulls more paint off the wire. It also causes more blending of paint injections and decreases image sharpness. It is very useful to increase air pressure when increasing spacer thickness between scrapers and increasing separation between the print head and media. Factory settings of scrapers, air presure, media separation, line spacing and percentage of paint printed are included in your software.   Facility Requirements for the WireJet 2 There are inherent problems associated with some paints and pigments. Facility requirements for safe operation of the WireJet 2 are identified as follows: (1) A separate room should be dedicated to the WireJet. Personnel should not be in this room during the operation of the WireJet so as to avoid excess exposure to airborne paint or pigment. (2) The room should be ventilated. An exhaust fan should duct to the outside. The exhaust fan should create a negative pressure in the room so that paint fumes do not infiltrate into the rest of the facility. (3) Protective clothing, gloves, vapor shielding glasses, and most importantly, a dual respirator should be worn by personnel while in the room or handling paints as required by the paint/ink manufactures warnings. Remember that the paints are airborne and may come in contact with the skin, eyes, or lungs unless proper precautions are taken. (4) UV flourescent lights may be required to convert some airborne paint particles to solids. (5) The ceiling to which the WireJet is attached should be capable of supporting 300 hundred pounds. The ceiling should be absolutely rigid. Additional support braces and beams should be added as required. The ceiling area above the wall used by the WireJet should be clear from obstructions. The WireJet will require a wall width of 22 feet (6.7 meters) for 16 foot (4.8 meter) printing using a standard 20 foot beam. The "width overhead" is: 56". The ceiling should be at least 8' tall (10' or 12' is preferred). The "height overhead" is 34" which means that the ceiling height less 34" is equal to the maximum output height. The width of the wall can be less than 22 feet. The beam and total print width will be correspondingly shorter. (6) The wall that the WireJet travels and to which the media is attached should be flat and ridged. For highest quality output, the flatness of the wall should vary no more than .050". This flatness is achieved by mounting tiled sheets of particle board across the entire wall area. It is very helpful if the entire wall slopes 2" for each 8' so that the WireJet has some small force of gravity always forcing the machine towards the wall. The wall should be at least 22 feet wide and 8' tall. The wall should be free of obstructions. There should be no switch plates or electrical outlets on the wall in the painting or overhead areas. The width of the wall can be less than 22 feet. The beam and total print width will be correspondingly shorter. (7) The air supply should be capable of delivering 4 SCFM (standard cubic feet per minute) at 40 psi. A regulator should be used to accurately adjust the supply pressure to the WireJet. The regulator should allow the air pressure to be set between 8 psi and 40 psi. The air pressure used is dependant on the desired quality output, speed of painting, media, and paint used. A dehumidifier should be added to the air supply. Water should be drained daily or as often as is required. Water in the air supply will ruin the output. The highest quality output will be obtained with dual regulation in the air supply. Dual regulation is achieved by first regulating the compress supply to some value like 60 psi. The regulated supply should then be fed into a tank through a second regulator to the final pressure as it is fed to the WireJet. The second tank and regulator will virtually eliminate compressor cycling and the small pressure variations because of it. The small pressure variations can cause banding in the output because more paint will be removed from the wire and spread differently with even slightly higher air pressures. (8) The WireJet uses less than 700 watts of power. The power should not be interrupted during painting. Because the position of the motors is not actually known by the computer, care must be taken to reset the WireJet if the power has been interrupted during painting. All motors should be manually taken back to the standard start locations using the Jog Motors... menu. The WireJet power supply ordered for  220 volts input. (9) A small table and chair are convenient accessories in the WireJet room. The WireJet paint head can be removed and set down for maintenance on this table. This table should be close to the computer so you can perform certain maintenance operations (like replacing the wires) which require the assistance of software control.   Gas Masks and Safety: (1) The WireJet produces air-borne paint. Many types of air-borne paint are extremely dangerous to your eyes, lungs, or skin. Consult with the paint manufacturer. Please make sure all precautions are taken as discussed in the section of this manual: "Facility Requirements for the WireJet". (2) The WireJet is heavy! The WireJet can jump off or fall during maintenance or if cables and ropes become tangled in the roller chain sprockets. A falling WireJet can hurt you or the equipment! Make sure that no cables or ropes become tangled in the roller chain sprockets. When performing maintenance or installation or during periods of storage, secure the WireJet with ropes. (3) Very powerful motors are used to drive the WireJet. The torque in the z-axis is multiplied 40 times! Hundreds of pounds of force can cut off a finger or do other serious harm! Do not put your fingers in the equipment when it is moving! You can shut off the power at any time and not harm the equipment. (4) The WireJet enclosure contains high voltage switching motor drives. There is a lot of direct current energy stored! Use the appropriate fuse protection in case of fuse failure. Do not use if the floors are wet!   Patent WireJet is a Registered Trademark of Dean R. G.
