Photo printing at home is a waste of time.
LAMINATION
The ink used in inkjet plotters is alcohol or waterbased. A sweaty palm will streak it completely(except for special waterproof media like banner vinyl). We normally heat encapsulate the output (hot-roll laminate both sides with a heat sealed edge) immediately to avoid moisture or fingerprint handling damage. We strongly recommend against handling unlaminated inkjet without wearing photo gloves. Sneeze on it and it's gone!
Once laminated, the output is very robust and can even stand up to rain.
However, three to six months of direct sunlight will severely bleach many normal inkjet colors.
UV resistant laminates and pigmented inks are now available that substantially lengthen useful injket life. They require more testing before realistic guarantees can be made. However, we think as much as two years with minimal fading is possible even in adverse positions recieving day long direct sunlight.
Our regular laminate is either gloss or luster (matte) finished.
Gloss laminate really makes the colors pop and enhances the photographic effect.
Gloss laminate does produce reflections and may not be suitable in a highly spot lit booth.
Luster laminate somewhat tones down the color and does not produce as much reflection.
In addition we offer a dry erase surface laminate for posters or adhesive backed film that may be then mounted to any substrate.
USING FINISHED INKJET
Laminated or unlaminated, the inkjet output may be rolled for shipping or storage. Velcro, magnetic strips or two sided tape can be applied to the back for fastening to a display. It may also be laminated to a variety of substrates as required. These include Coroplast, Sintra, Plexi, Foamcore, Posterboard and Lexan.
THE SPECIFICS OF DIGITAL INKJET
Newer computer design programs allow fast creation of full color, easily changeable designs. Your possibilities for utilizing situation specific, one or short run output has exploded. Several systems have been developed to provide such output. The most cost effective is inkjet technology.
Inkjet plotters produce rich, vibrant colors for type, drawn artwork or photographs. From a normal display-viewing distance, the look is that of a color photo.
1200 Dots Per(DPI) Inch Inkjet printing produced with the right quality inks, media, high resotution input, superior RIPs and expeienced operators produces photo quality results. This technology evolved from plotters used in the CAD world. Roll media is used, so length of output is ruled by the computer capacity and software driving the plotter. Sizes presently are up to 60 inches in width by approximately 100 feet maximum length.
Output from modern Inkjet Graphics Plotters is true four color and can be made to a variety of materials, then be laminated or mounted for display. Resolution is up to 1200 DPI. From a few feet it normally will appear as continuous tone of photographic quality. Photos captured with high resolution drum scans appear with excellent detail and quality. Lower resolution flatbed scans, photo CD and even jpeg files produce very acceptable display quality results, particularly for larger sizes to be viewed from more than 5-10' distance. Colors are rich, fully saturated and vibrant. The overall quality of 1200 DPI Inkjet exceeds Electrostatic sinificantly. From longer distances the resolution difference between Inkjet and Electrostatic is less, but electrostatic colors are just not as rich & vibrant.
This is the highest quality/value for money choice until the number of pieces required reaches a level where screen printing becomes cost effective.
The standard inks used in Inkjet plotters will not resist direct sunlight (UV) for more than a few weeks. Newer UV resistant inks can resist sun for six months up to one year or with pigmented inks more than a year, depending on how the output is finished and mounted.
Large billboard or mural size displays can be achieved by paneling 60" wide strips of inkjet output thereby creating giant wall size, near photographic quality backdrops.
Inkjet output can also be laminated or mounted to a variety of other materials for application to trade show booths, store displays or other special purposes.
