Multispectral printer characterization requires an effective model to map the inputs to the printer (i.e., the digital counts of the inks) into reflectance spectra and vice versa. Most of the methods for printer modeling are based on the color mixing model of Neugebauer, but this model, in its original formulation, is a rather poor predictor of the printer's output, since it fails to take into ...

Ink-jet printing is a promising deposition technology, which capable of large-area fabrication and mask-free patterning. For ink-jet-printed quantum dot (QD) light-emitting diodes (LEDs), the QDs are commonly dissolved in mixture solvent thickener ink system. However, hole transport layer could be eroded by this QD ink, leading to rough surface morphology resulting leakage carriers low device p...

The realization of a wavelet-based iterative learning controller (WILC) is presented in this paper. To meet the requirements of simplified hardware, fast rapid prototyping and fast up-date cycle, a wavelet-based iterative learning control system is implemented on a single FPGA (Field Programmable Gate Array) . There are three modules in this FPGA-based system, they are a feedback module, a disc...

In order to the increase sensitivity of enzyme-linked immunosorbent assay (ELISA) using micro-droplet reaction system formed by ink-jet, we employed small dots of two-dimensionally well-ordered structure of polystyrene (PS) microbeads (710 +/- 25 microm in diameter) formed on the surface of polydimethyl siloxane (PDMS). An aqueous suspension of polystyrene microbeads (5 microm) was ejected on t...

Se pot obţine prototipuri de, aproape, orice complexitate geoemtrică, într-un timp, relativ scurt, prin Prototipare Rapdă, tehnologia de fabricare abordată fiind cea a fabricării “aditive”. Lucrarea evidenţiază importanţa tehnologiei de prototipare rapidă, prin imprimare cu jet,”Ink-Jet Printing”, în design-ul unui reper component al unui produs foarte important şi scump. S-a obţinut prototipul...

This article presents a numerical model that was developed for the drying of ink-jet-printed polymer solutions after filling the pixels in a polymer LED display. The model extends earlier work presented in the literature while still maintaining a practical approach in limiting the number of input parameters needed. Despite some rigorous assumptions, the model is in fair agreement with experimen...

A new measurement method is proposed to separately measure the effect of ink spread and optical dot gain on the MTF (modulation transfer function) of printed images from an ink jet printer. The transmittance and reflectance of the same printed images are captured with two different illuminations: one on the printing surface (for measuring reflectance) and the other through the paper base surfac...

Non-contact micro dispensing technologies have turned out to be ubiquitous tools in various industries and applications over the past decades. The well-known ink-jet printing technology – to give a prominent example – has paved the way to digital printing and still plays an important role in industrial fabrication together with micro-dispensing valves used in a large variety of applications. Th...
