2. Inkjet printing - Wikipedia

   en.wikipedia.org/wiki/Inkjet_printing

   Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. [1] Inkjet printers were the most commonly used type of printer in 2008, [2] and range from small inexpensive consumer models to expensive professional machines.

4. Polyethylene terephthalate - Wikipedia

   en.wikipedia.org/wiki/Polyethylene_terephthalate

   About 60% crystallization is the upper limit for commercial products, with the exception of polyester fibers. [ clarification needed ] Transparent products can be produced by rapidly cooling molten polymer below the glass transition temperature (T g ) to form a non-crystalline amorphous solid . [ 34 ]

5. Dot gain - Wikipedia

   en.wikipedia.org/wiki/Dot_gain

   As printing pressure can squeeze the ink out of its dot shape causing gain, ink viscosity is a contributing factor with coated papers; higher viscosity inks can resist the pressure better. Halftone dots can also be surrounded by a small circumference of ink, in an effect called "rimming".

6. Polystyrene - Wikipedia

   en.wikipedia.org/wiki/Polystyrene

   Polystyrene foams are 95–98% air. [43] [44] Polystyrene foams are good thermal insulators and are therefore often used as building insulation materials, such as in insulating concrete forms and structural insulated panel building systems. Grey polystyrene foam, incorporating graphite, has superior insulation properties. [45]

7. Polymer - Wikipedia

   en.wikipedia.org/wiki/Polymer

   Polymer properties depend of their structure and they are divided into classes according to their physical bases. Many physical and chemical properties describe how a polymer behaves as a continuous macroscopic material. They are classified as bulk properties, or intensive properties according to thermodynamics.
