The Determination Of Using The Standard Screening Angles When Printing With 400-Count Anilox Rolls And 100 Line Images Via Flexography, John Ahrens
Theses
From the pioneering efforts of the early 1960 's, flexography has shown steady progress in the development of four color process printing. However, the ability to consistently produce it is limited to an elite group. The vast majority of companies have yet to competitively enter this demanding area of printing. For these companies the time, expense, and expertise required to conduct an indepth study is a major deterrent. Outside information must be made available to aid the companies. The FTA and its members have greatly contributed by publishing an array of information; although, some basic questions have yet to be …

Plate Stability In Screenless Printing, Stephen E. Martin
Plate Stability In Screenless Printing, Stephen E. Martin
Theses
Lithography in the minds of most people is a method of reproducing a photograph or artwork by means of a halftone screen. The screen, usually no finer than 400 lines per inch reproduces the image by varying degrees of density through control of the dot size. With screenless printing the image is reproduced without the screen, resulting in much better detail. The purpose of this thesis is to determine what type of plate material will work best with the "Association Product Coating", since the ST Sumner Williams plate that worked well with this coating is no longer produced. The criterion …

The Verification Of An Optical System Design For A Low Frequency Mtf Camera, Edwin B. Hoel
The Verification Of An Optical System Design For A Low Frequency Mtf Camera, Edwin B. Hoel
Theses
A proposed low frequency MTF camera system uses a cylinder lens to smear an area-modulated sinusoidal target into an irradiance-modulated sinusoidal image for the evaluation of a film's modulation transfer characteristics. The proposed system was constructed and evaluated. Resolution limits, field flatness, field sharpness, repeatability, de focus effects and system MTF were determined. The camera was tested with film and found to have an MTF value close to 1.0 for frequencies up to 10 cycles/mm at which point the function dropped off to a value of 0.2 at 30 cycles/mm. Off-axis images showed rapid degredation as a maximum MTF value …
The Design And Construction Of An Exposure Meter For Use With Infrared Sensitized Film, James A. Fitz
The Design And Construction Of An Exposure Meter For Use With Infrared Sensitized Film, James A. Fitz
Theses
In this project, an exposure meter which is sensitive to, and calibrated for infrared radiation was designed and constructed. An EG&G SGD-100A silicon photodiode was chosen to use as the photodetector. This choice was based on cost, availability, ruggedness, stability, and sensitivity. A circuit using an operational amplifier to amplify the output of the photodetector was used. The circuit design allowed easy variation of the signal gain to give a detectable meter deflection under varying lighting conditions. Five different gains were used to allow use of the meter under conditions ranging from outside under direct sunlight, to inside with typical …
Agn03 And Kbr Reagent Concentrations' Effect On Double-Jet Emulsion Grain Size Dispersity, Daniel D. Siems
Agn03 And Kbr Reagent Concentrations' Effect On Double-Jet Emulsion Grain Size Dispersity, Daniel D. Siems
Theses
Four levels of AgN03 and KBr reagent concentrations between 0.1N and 1.0N were used to study the effect of changing reagent concentration on the grain size dispersity of a primitive AgBr double-jet emulsion. The emulsions were precipitated in a continuous flow crystalizer at a constant pAg of 8.5 within the crystalizer. Emulsion samples were collected at 5 minute intervals during the make from the crystalizer and used to obtain grain size frequency distribution data. Through the use of multivariate analysis of variance, it was concluded with 95% confidence that AgNOo and KBr reagent concentrations ranging from 0.1N to 1 .ON …

An Investigation On The Applicability Of Multi-Microprocessing In The Two Dimensional Digital Filtering Problem, Timothy J. Whitcher
An Investigation On The Applicability Of Multi-Microprocessing In The Two Dimensional Digital Filtering Problem, Timothy J. Whitcher
Theses
Digital image processing has been receiving an increasing amount of development in recent years, largely because high speed digital com puters are becoming readily available. In addition, the advent of the microprocessor has revolutionized the capabilities of compact electronic systems. This thesis examines the applicability of microprocessors to digital image processing. Using a Z8000 microprocessor as a baseline, the computation time for a two-dimensional fast Fourier transform is estimated for various microprocessor architectures. These results are later compared to the manufacturer's specified computation times on a Floating Point. Systems AP-120B Array Processor.

Widestock Exposure Modification, Kurt D. Roberts
Widestock Exposure Modification, Kurt D. Roberts
Theses
A system exists for the exposure of large pieces of sensitized material. The strips are exposed, processed, and viewed by transmitted light. This procedure is used to gauge the quality of the film coating process. There are three problems with the existing system: uneven illumination, the timers do not take into account light decay, and finally, the operators, on occasion, set up the wrong conditions for an exposure. The purpose of this thesis is to modify an existing process for the automated exposure of wide stock strips. These modifications are to replace the system's components with state of the art, …

Signage System For Abuja Internation Airport, Abuja Republic Of Nigeria, Hilary G. Marquis
Theses
The purpose of my thesis is to design a signage system for my country's new capital city international airport now under construction at Abuja. Although this project is not a professional contract, I have chosen this topic because of the almost true-to-life experience it has afforded me in working closely with government agencies. It is hoped that this contact will help government managers and planners understand that large construction projects need well thought-out environmental graphics programs. This signage system is designed specifically to orient passen gers from the point of entry on the airport premises to their leaving through the …

Design, Construction, And Verification Of A Photographic Color Paper Sensitometer, Daniel Marc Denkin
Theses
The thesis problem is to produce a sensitometer to expose photographic color paper to be used as control strips in a photographic color paper process. This problem involves designing, constructing, and verifying the sensitometer. Designing the sensitometer is done by looking at different methods of exposing each dye layer of a photographic color paper. These methods include: fiber optics or light guides, light integrating devices, and projection systems. The method which was chosen for this experiment is the projection system. After the method had been decided upon, a lamp model will be calculated using the spectral sensitivity curve of a …
Ultrasonic Flaw Detection, Wayne Buchar
Ultrasonic Flaw Detection, Wayne Buchar
Theses
An ultrasonic microscope was designed and constructed to detect surface flaw defects on materials which contain natural discontinuities. The application of this flaw detection system to via-fill defects of single layer multiple layer ceramic substrates was considered. The microscope was evaluated for its depth sensitivity and resolution capabilities. The results of the experiment are that the ultrasonic system has repeatable depth sensitivities of better than ten microns, and resolution capabilities on the order of 3.3 cycles per millimeter. The application of the flaw detector to ceramic substrate via-fill defect inspection was verified.
Halftone Dot Method For Image Evaluation Of High-Resolution Films Applied To Vesicular Film, Mark Gulden
Halftone Dot Method For Image Evaluation Of High-Resolution Films Applied To Vesicular Film, Mark Gulden
Theses
A feasible technique for deriving the spread function and modulation transfer function of a vesicular film has been determined. This technique is based on a method described by R. Byer which does not require the use of a microdensitometer, but only that of a "macro" densitometer. The method utilizes the fact that a halftone dot will change in size as a function of exposure. The spread function of the vesicular film was approximated with a mathematical model. The results, although favorable in many ways, are not conclusive. Some of the advantages and disadvantages associated with this technique as applied to …
