Test #1: Measurable Print Characteristics
Theoretical Concepts
What Are We Testing?
Determining dot gain, print contrast and ink trap allows us to analyze press sheets and colour bars to find the most favourable running conditions to reproduce a proof for a job. In order to retrieve these print characteristics, multiple density readings are taken with a densitometer from the print control strip to interpret values and use them to asses quality. Dot gain (or tonal value increase) is the increase in the size of a printed dot from plate to press sheet (also in prepress from file/film to print). Dot gain occurs in every printing process and are “most visible in the midtones and deep shadows” (Lawler, 1995), by testing gain and using the dot area equation – a set of adjustment values can be decided upon for how to print the rest of the job. Proofs with high contrast have greater shadow detail - d...
This is a written report where my partner on the topic and I presented a ten minute oral summary of our chosen research topic on Technicolor. We chose Technicolor as we felt it had most to say to us, threw the progression of the technology the problems threw out the years of perfecting the technology, to the ultimate glory of the Technicolor experience.
1. In each case, is the ink a pure substance (based on your results)? Why or why not?
The essay “Tlilli Tlapalli: The Path of the Red and Black Ink” written by Gloria Anzaldua grants the reader insight into a writer's mind. The essay reveals the reasons and process of becoming a writer and therefore an artist.
Throughout history, there have been many inventions to help humans communicate, such as the telephone, typewriter, and many more. One great milestone was the printing press. The printing press was invented in 1,450 CE by Johannes Gutenberg. The printing press is a machine that could quickly mass produce books at a cheap cost. He created the invention in Germany. The printing press lead to a higher distribution in books at a lower price. As a result, the literacy rate was increased and more people were able to learn about science, religion, and geology.

Paper Planes Sometimes Australian cinema can be overlooked in many international markets, and even domestically as the distributors needed to gain worldwide attention are not generally signed with the productions. Coupled with the different setting and characters as of other Hollywood films, makes the Australian film genre a difficult sell to many international markets. This was clearly evident in the 2014 Australian film Paper Planes. Paper Planes was released here in Australia theatrically on the 15th of January, 2015.
PRINTING PRESS AND STANDARDISATION In 1476, William Caxton introduced England to the printing press. This significant introduction to one of the world’s greatest technological innovations, at the time, helped to increase the spread of literacy and knowledge amongst the British people as the mass production of books became cheaper and more commonly available. According to Mastin (2011), the first book ever printed, although Caxton’s own interpretation was ‘The Recuyell of the Historyes of Troye’ in 1473. Furthermore, Mastin (2011) states that in the following 150 years after the introduction of printing, up to 20000 books were printed.
The most common cause of external bleeding is an injury. Any type of cut, scrape, or fall where blood is coming from an open wound is regarded as external bleeding. The type of blood vessels damaged in a cut determines the speed at which blood is dispersed from the injured area.

We then placed several dots as specified by the lab protocols, for instance placing a pencil dot in from the edge. Then, using a capillary, we spotted the 3cm spot about five times with spinach extract, that was obtained in column chromatography. Students, the placed a spinach leaf on the paper, covering 7 and 10cm dots. Using a quarter, students rolled over the leaf from about the 7 to 10cm mark several times. We then rolled the paper into a cylinder and stapled it. Once the paper was placed in a beaker containing 30ml of 90/10 hexanes to acetone mixture, foil was placed on top. Once the solvent reached about 1cm from the top of the paper, we took it out and marked the solvent front and again outlined every spot. We again, measured the distance to the solvent front and to the center of each spot—and calculated the Rf values for each spot. The colors for each spot, for both this and the paper chromatography were
The idea was to improve 3d printer with special technology, a single printer, with multi material features, can transform from any 1D strand into 3d shape, 2d surface into 3d shape or morph from one 3d shape into another. The shape of 3d technology is basic mode for 4d. Objet Connex multi-material technology is an 3D printing important part of his work – and is being used extensively in this new process. The Connex multi material technology allows the researchers to program different material properties into each of the various particles of the designed geometry and harnesses the different water-absorbing properties of the materials to active the self-assembly process. With water as its activation energy, this technique promises new possibilities for embedding programmability and simple decision making into non-electronic based materials.
When conducting marketing research it is imperative to comprehend the different types of measurement scales in order to properly apply or use them in the collecting data process. Also selecting the right measurement scale is key to assist researches in collecting quality data. According to Hyper Stat, 2011, Measurement scales are use in the assignment of numbers to objects or events in a systematic fashion. Four levels of measurement scales that are commonly distinguished are nominal, ordinal, ratio, and interval scales. In this paper the author will describe each one of the four measurement scales and discuss how they can be use when developing a questionnaire.
