Rheology versus Viscosity

  • August 28, 2021
  • Comments off

Rheology is a branch of physics or physical chemistry. Viscosity is a quantitative measurement that is useful in chemistry. These two terms are related to fluids such as liquids and gases. The key difference between rheology and viscosity is that rheology is the study of the flow of matter whereas viscosity is a measure of […]

As screenprinters, we often rely on our intuitions to help us make decisions. And while intuitions have some basis in business, we must look a little deeper. In business, it’s quantification – the numbers – that prove (or disapprove) our feelings. Quantification fuels innovation!

The Problem of Bias

  • August 25, 2021
  • Comments off

Why Peer Review is Important to the Screenprint Technologies Peer review is long overdue in the myriad technologies of screenprinting. Every month, screenprinters are presented with biased misinformation that creates a massive amount of waste in the industries. Nothing is more important to the tens of thousands of shop owners and those who work in […]

Friction versus Shear

  • August 21, 2021
  • Comments off

Friction and shear stress are two phenomena involved in the field of mechanics of matter. It is very important to have a good understanding of both friction and shear stress in order to get a good understanding of fields such as screenprinting, electrical engineering, automobile engineering, mechanical engineering, and any other relevant field. Both friction […]

Average Velocity versus Velocity

  • August 14, 2021
  • Comments off

Velocity is a very important property discussed under the field of mechanics in physics. The velocity of an object describes how fast the object is moving and the direction of its movement. The average velocity describes the overall effective velocity of a motion. Both of these concepts are fairly basic and very important in almost […]

Deformation versus Strain

  • August 7, 2021
  • Comments off

Deformation is the changing of the shape of a body due to the forces and pressure applied to it. Strain is the force created by the elasticity of an object. Both deformation and strain are two very important concepts discussed under material science. These concepts are vital in the course of understanding subjects such as […]

Newtonian versus Non-Newtonian Fluids

  • August 4, 2021
  • Comments off

The name Newtonian comes from Isaac Newton, who was the first scientist to use a differential equation to postulate the relationship between shear stress and the shear rate of fluids. We can divide fluids, i.e. liquids and gases, as either Newtonian or non-Newtonian depending on the viscosity of the fluid. Viscosity is the state of […]

Film Positives Adhering to the Stencil

  • August 4, 2021
  • Comments off

The number one reason that inkjet film ink adheres to the stencil during the exposure process is that the ink and/or the stencil were not dry. Many screenprinters use inkjet printers to produce film positives that are used to transfer the image from the computer to the stencil. While inkjet films are less expensive than […]
