The relation between print heads and pL( picolitres)

PL or picolitres is often referenced in specifications for modern day  ink jet wide-format printers Picolitres is a terminology  in industrial printing that represents ink droplet size emitted from a print head. The general rule regarding droplet size is that the smaller the size of the droplet is  the greater is the final print detail. However, this is a generalization that does not work in a linear motion for wide-format principles. The picolitre is valued as fraction from a litre and it denotes the measure for dispensed ink volume, therefore its role is significant for quality but also depends on various other factors like weather and types of inks. For example in a humid or a hot country if you run a wide-format printer with 15 picolitre droplet with inks that are solvent based, it can create more problems than using same measure in UV-curable inks that remains in liquid state till it is cured. One of the better print heads based on performance standard is the Fujifilm’s Dimatix Q-class like Spectra Polaris 512 15 PL. 

 

 The relation between Print heads and Picolitres:

 It is established that larger picolitre size means bigger droplet but it is also important to find out the ink type in the printhead and whether it is grayscale or binary. Solvent based inks are more fastidious to handle in terms of maintenance because the heads can be clogged with the ink. That means the smaller you on the picolitre size the more efforts in nurturing the machine is required. Fujifilm’s Q-class Spectra Polaris 512 35 PL is worth a check out as it is just the right print head for industrial purpose.

 The purpose of creating better technology in printing is to achieve end result with less effort and less troubles with the machine later. And picolitre of printhead does help in determining the print details but it is one element among many responsible for fine printed result. Larger picolitre size means lower final resolution but they need fewer passes and fewer passes have their benefits in wide format printing. On the other hand small picolitre size creates finer result but requires many passes and there are cons of having many passes. Spectra Polaris 512 15 PL (picolitre) is a perfect match for high performance printing needs.
