In the past, the primary focus of new inkjet technology development was in the increase of print resolution. By the use of smaller and more accurately placed drops, clever image processing/ manipulation and greyscale techniques, inkjet has reached the limit of what the human eye can differentiate (evidenced by toda) s low cost, ultra-high image quality consumer printers). 

State-of-the-art piezo-based drop-on-demand printers are produced by companies such as Xaar (UK), Konica Minolta (Japan), and Fujifilm Dimatix (US). These print heads have around 180 to 360 nozzles per inch and are designed to print at basic resolutions of up to 360 dpi with drop volumes down to about 40 pi (picoliter). This type of print resolution gives features equivalent to approximately 100 /xm track width on PET or PI substrates. However, Xaar s new generation "gray scale" heads allow variable drop volumes down to around 3 pi to give printed features of around 50 /xm or less. 

The 3D Systems Thermojet Printer [38] also uses a demand mode piezoelectric array printhead dispensing a thermoplastic material to build solid models. Printing resolutions (actually addressability) of 300, 400, and 600 dot per inch (drop spacings of 85 pm, 63 pm, and 42 pm) are claimed. The maximum model size is 25 cm x 19 cm x 20 cm.

Figure 4.13 illustrates several techniques for patterning PEDOT PSS via electrochemical overoxidation. Conversion of a simple plotter pen or a screen-printing station are relatively straightforward, the latter allowing print resolution of a few hundred micrometers. To demonstrate that the technique is limited only by the resolution of the printing method, 2 p,m lines (the smallest mask available) were patterned in a 200 nm thick film with the aid of a photoresist mask [29]. 

Control over the formation and delivery of the ink drop is crucial, for the ink drop becomes the printed dot as it lands on the substrate (Wijshoff, 2010, p. 85). A combination of factors, detailed across the chapters of this book, contribute to ink jet printing success, including the print head that forms and delivers these dots as critical for print resolution, quality, and speed. Key points to note in drop formation and delivery, by any form of print head, are ... 

Ethyl acetate is a solvent found in nature and is environmentally safe and acceptable for food applications. For instance, it is used in the packaging industry because it provides high printing resolution on plastics and metals. D-Limonene is a major compound found in oil extracted from citrus and is present in orange and fruit juices. It is also used in cleaning products as a solvent or a water dilutable product. It is a very versatile chemical and therefore used in a wide variety of applications. Scalping of D-limonene from... 

Poor print resolution simply means that the printed film does not match the layout in terms of dimensions or shape. It can be because of spreading of the print because of improper rheology, or a flaw in the screen. These factors help to improve resolution of the pattern [29-31] ...
