HP Technology in the Industrial Environment – Will it Work For You?

As a commercial printing specialist for several years I have actually viewed the markets innovations expand and essentially enhance the high quality of print as well as lower the upkeep and price per print. The most recent addition to the field has been using common HP printer cartridges for item marking and external situation coding. This modern technology and a lot of its capability has actually been developed in the printing market on big internet and also in the mailing market to attend to information Website.


Control is the trick

The drawback to this printing modern technology is there are too many things that need to align to accomplish high quality print. The present Spear and Zar print engines are a single row of multiple nozzles. With the HP style system the ink cartridge itself has 2 networks one close to the various other and also the 2nd row of nozzles has to publish exactly over the first row of nozzles or a ghost or blurry print is developed. This is a lot less apparent in text printing yet can be a catastrophe when publishing graphic images or barcodes. The majority of makers have consisted of the capacity to turn off one set of nozzles 150 DPI vs. 300 DPI. The print with just one channel allowed is half the darkness and if a nozzle in the cartridge stopped working or ends up being obstructed a clear line will certainly exist in the print.

The 2nd alignment comes into play when more than 1/2 inch tall characters or barcodes have to be printed. This is attained by piling numerous cartridges alongside each other in a gradually greater pattern. This calls for the 2nd print cartridges publish details to be flawlessly timed to straighten with the previous print and so on for each added cartridge. Unlike a house inkjet printer where the paper feed is regulated and also the print cartridge speed as well as placement is regulated in a production atmosphere the cartridge is stationary and the product printed on is removaling.

The ink cartridge has little to no “throw range” so the print head has to be placed very close to the product being published on. Again on an internet application or a vacuum table this is conveniently accomplished. On a conveyor however the box or instance must be appropriately lined up to the print heads to attain top quality print. If the instances or boxes are not appropriately put up and loaded to keep a square profile they will frequently catch on the print head or drag when passing as well as being published. Bear in mind all that timing as well as alignment I stated above? The placement of the print is only regulated by the timing of the print cartridges. If the material drags or transforms speed that timing is shed and all those placements fail. Encoders are created to change for rate adjustments in the conveyance system however if the material speed does not exactly match the transportation systems speed you loosened!

It’s Clean, Easy, and also there is No Upkeep

All three of these statements hold true, the water based inks used in a lot of these print systems is much cleaner that the oil based inks made use of in the Trident and Zar innovations. No maintenance can be a double bordered sword with these design printers. Where incorrect cleaning of a Spear, Zar, or Decline on Demand printer can cost thousands out of commission and also requires adequate training the oil based inks do not dry so they stay all set to print. The HP cartridges need gotten rid of and covered when not being used and also are conveniently changed by any type of staff member. This could potentially cause your ink prices to skyrocket if your staff finds it simpler to promptly replace a cartridge instead that clean as well as purge the system. Removing is a feature that sprays ink from the nozzles in an effort to clear small obstructions. Your office or home printer does this regularly; these systems require you to do it by hand within the software. A cartridge that ought to give you thousands of prints can conveniently be thrown in the garbage and also replaced after just a couple of hundred prints. 10 times the original expected expense. In a high volume application there are bulk ink systems available. Remember that each cartridge in a numerous degree setup requires a separate ink degree. To high a degree and the cartridge will certainly leak, to reduced and also it will certainly deprive and air will certainly be sucked in through the nozzles. I have actually seen only one bulk ink system that functions well. As you possibly could think it was developed and designed by HP as well as is limited to the inks they produce. Be absolutely certain that the expense savings of a bulk system surpasses the upkeep and frustration of a poorly made system. Additionally bear in mind the price of bulk cartridges is greater than a single usage cartridge however can be changed and also disposed of just as promptly.

Is this kind system right for you?

If you are printing a solitary line of print less than 1/2 inch high and also much less that 20 personalities it is an excellent system for you. You will not have the positioning issues with a numerous head system. Most other systems will be designed to print one to 3 inches of print so the cost will be greater for functionality you do not need. I restricted the print to 20 characters given that consistent rate while printing is much easier to maintain with smaller sized length prints.

If you call for a multiple cartridge system you will have to guarantee you can supply the adhering to.

If you call for a multiple cartridge system you will should ensure you can give the following.
The material to be printed on have to be square. Uneven or bulging situations will certainly not be printed well. Skewed instances will bind and drag when crossing the print head and also provide blurry or ghost printing.
Conveyor systems must be smooth as well as consistent. Since the print head is fixed and the material remains in motion, the opposite of a home or office printer, absolute speed control is a must for these systems.
Discussion to the printer need to be perpendicular and square to the head. With little to no capacity to print throughout any kind of air space distance the product being published needs to be as close as feasible without dragging the print heads. This needed the range to continue to be the very same top to bottom and as the product passes side to side.

This sort of printing innovation has actually been in usage and verified to work well. All of us have some type of ink jet printer in our residences and workplaces. Regarding I realize they all print with the cartridge nozzle facing down. I have discovered there are numerous damaging problems that emerge when these cartridges are related to publish on a straight rather than vertical level.

I have has wonderful success with this modern technology in very regulated atmospheres like drugs, cosmetics, and also laboratories where the products and products are included during transportation and are generally robotically managed. Printing on an upright plain has actually likewise increased the stability of these systems.
