The main photo machine a few parameters
Posted:2011-7-23  text 〖 Large mid Small 〗  Views:   [close]
Nozzle: nozzle into hot foam and micro piezoelectric nozzle two, because the photo machine is the most important parts, so we will specifically discuss later, there being ignored.

Width: Most photo machines on the market will focus on the effective width of 130 cm (50 inches), 152 cm (60 inches), 160 cm (64 inches), 180 cm (74 inches) to 160 cm machines on the market most sensitive. At present, domestic supplies standard as follows: 0.914 m, 1.06 m, 1.27 m, 1.52 m, 1.27 m below the screen in which the majority. Width width of sub-feed (also known as material width), and real spray width (working width), the former often large 1 inch (2.54 cm) or more.

Accuracy (resolution): Many people do not understand, "photo opportunities" refers to what a static photo printing another photo, where the means to achieve close to photo-quality precision, usually 720DPI, describes the general indicators of the accuracy of Printer dots per inch, that DPI (Dots perinch), accuracy is determined by the nozzle, the same nozzle with the same accuracy. Early photo printing accuracy is generally 300DPI or 360DPI, the mainstream products currently on the market is 600DPI (HP, ENCAD) or 720DPI (MIMAKI, ROLAND, MOTOH), some products of the highest resolution up to 1440 × 1440DPI (MIMAKI, ROLAND , MOTOH) or 1200 × 1200DPI (COLORSPAN), along with advances in printing technology, such as EPSON latest 6pi ---- invisible ink droplet inkjet technology point of emergence, DPI number will further increase, but accuracy by the computer processing speed, storage capacity, image source, printing materials, ink and other constraints, to be synchronized with the development of these technologies is significant, the practical application of the general advertising graphic precision 600DPI to 720DPI is adequate used, higher accuracy may be only selling products only. In fact, many users in the use of advertising 360DPI, 540DPI, 720DPI 8PASS is the highest output mode, and going up all the supplies you need to use the original order to reflect the slight details of the effect of improving the quality of print is not clear how, but print speed will be substantially reduced, more importantly, head loss is too large, have added unnecessary costs, it is worth the move. According to my view, in addition to the initial purchase when the test machine, the more than 95% of users probably will not in this life is not practical to use 1440DPI for more than a "precision" to give customers the map. EPSON is currently the fourth generation of the most high-precision nozzles 1440 * 1440DPI, higher "accuracy" is only some of the dealers hype too!

Output speed: the speed of the suppliers generally not comparable, because there is no description of the specific test conditions and the state, the individual will be divided into "draft mode", "photo mode", but customers still do not understand. Affect the actual printing speed factors are: A: Equipment pure printing speed, B: Software RIP speed, C: data transmission speed, drying time. Simply printing speed and patterns, mode of decision factors are: accuracy, PASS number of single two-way, heavy spray frequency. Mainstream models sold in the market (MIMAKI, ROLAND, MUTOH) in the same mode, the speed difference between vendors is not released, the actual printing of the most accurate in the next 3 to 4 square meters per hour, the general accuracy of 14 ~ 28 m2 . In fact, the printing speed of the equipment itself, equipment, advantages and disadvantages of using the ink and equipment such as ambient temperature and humidity directly affect whether the long-term high-speed output rate of qualified products. At this point only through long-term use of the device more than 4 m above the print image can be verified, after all, equipment is often bought straight after work. This non-profits in todays era, with the production of quotations pour-style landslide, profit margins are compressed again, the majority of advertising production industry had no choice but to recognize such a fact - to meet the practical accuracy of the premise, the production rate, loss cost and stability of the device has become the key to profitability.

Consumables costs: direct costs of printing by the ink, substrate, nozzle wear and tear, film and other items of scrap composition. We usually only refers to the material cost of the first four combined. Because supplies are basically common to each other, HP, ENCAD the nozzle is replaced periodically, MIMAKI, ROLAND and the nozzle is free for the warranty, so the material cost of different inkjet printers only difference between the performance of the nozzles on the costs and scrap rates. Should also be noted that different brands and models Printer unit amount of ink is different, it is estimated that, per unit area of ​​HP, ENCAD out of ink than ROLAND, MIMAKI out of ink volume, but also slightly higher price compatible ink , in general, ROLAND, MIMAKI the use of cost or lower than HP, ENCAD. Currently ROLAND, MIMAKI compatible ink around 8 yuan per square meter, because compatible inkjet ink is to reduce the cost of the key, compatible ink decide the merits of the rejection rate and the nozzle is a key loss.

Color: we can not say, the more vivid the color the better, good or bad depends on its color gamut can show the size and restore consistency (uniformity within the gamut), from the color gamut in terms of: the human eye can feel the natural color > RGB color gamut> CMYKOrGr six color gamut> CMYK four-color field, so some colors are not printing out the expression in any case. The quality of color should be divided into indoor and outdoor both cases to analyze the judge. In general, a large indoor ink color gamut, printing some of the effect is more beautiful, and outdoor ink is darker than the gray. EPSON latest six-color system to some extent overcome this shortcoming: CMYKOrGr can expand the color gamut performance, especially in the orange and green parts; CMYKLcLm while enhancing color uniformity, so similar to human skin color part over more natural and realistic. MIMAKI JV4-160 and ROLAND FJ740 have adopted this six-color scheme, which is a technology trend. In fact, four-color machine in the advertising industry, the vast majority is sufficient to meet customer demand, MIMAKI JV22-160 and MUTOH RJ8000 dual four-color structure of the models, they are customized for the Chinese market a professional ICC curve, making the color performance is more realistic.

Outdoor UV resistance: the performance of the ink used mainly by the decision, all the basic original ink manufacturers are not universal, so each machine a different effect of UV inkjet ink are not the same performance.
