A Study Of The Subjective Differences Between Soft-Copy And Hard-Copy Proofing, Sandra Fuhs

Theses

The widespread use of Cathode Ray Tubes (CTRs) as soft-copy proofing devices in electronic imaging situations has raised serious questions as to their relevance, the appropriate viewing conditions and the necessary design, color and tone characteristics of the color monitors. Proofs are used at many different stages in the print production process. Each stage has different requirements in terms of color acceptance, detail, sharpness, composition and portability. At each level of the approval cycle various measuring devices are used to qualify acceptability. This thesis deals with every-day use and problems of soft-copy proofing. An electronic test pattern was displayed on …

A Colorimetric Analysis Of Color Variation Due To Changes In Simulated Ink Trapping, Mary Louise Bulger

Theses

The purpose of this study was to address, through colorimetric analysis, color variation as it relates to the efficiency of trapping. A developing awareness of colorimetric analysis in the graphic arts, as well as the realization of some of the limitations of densitometry when applied to color analysis provided impetus for such a study.

Comparison Between Edge Tracing And Slit Tracing In The Measurement Of The Otf, J. S. Perron

Theses

A study was performed to compare two methods of measuring the Optical Transfer Function (OTF), namely edge tracing and slit tracing, to evaluate the performances and limitations of each method. Edge tracing is a very common method of measuring the OTF of an optical system. It is simple to set up, but the sampling size is limited and derivation of the Edge Spread Function is required in order to obtain the Line Spread Function (LSF). This derivation induces considerable high frequency noise. A competing method, slit tracing, is more complex mainly because of physical limitations such as the actual slit …

Criteria For Identifying Artistically Talented Students In Elementary Education, Mary C. Tevlin

Theses

To objectively identify an "artistically talented'' student in an elementary art class is a difficult procedure. Many processes have been used in recent years in order to place these art students in gifted art programs.

This paper examines the literature describing many tests and procedures that have been used to assess students in the area of visual arts ability. It examines research identifying the behaviors and characteristics of visually talented art students and has formulated a questionnaire for teachers to use when identifying artistically talented students in elementary education.

The questionnaire was piloted in one school district. Revisions were made, …

Factors Affecting The Strength And Openability Of Tight Backed, Adhesive Bound, Hardcover Volumes, Geoffrey Hyatt

Theses

The practice of tight backing adhesive bound, hard cover books has long been thought to enhance durability at the expense of openability. Tight backing is popular in a number of specialized binding markets, the most notable of which is textbook production. Yet despite their prevalence, there is a lack of information available about how the openability and durability characteristics of tight backed books are affected by variable factors in the production process. The purpose of this study was to evaluate three variables involved in the production of tight backed, adhesive bound, hardcover volumes. The three factors considered were bulk of …

A Study Of The Effect Of The Francis Howell Writing Process On The Language Arts Achievement Of Fourth Grade Students, Carolyn Rose

Theses

During the 1986-1987 school year, the Francis Howell School District implemented a formal writing process designed to address students/ deficiencies in language arts. An attempt was made to demonstrate the effectiveness of this program by examining the differences in language arts scores on a standardized achievement test between a class of fourth graders which was not exposed to the writing program--the comparison group, and a similar group which received instruction based on the Francis Howell Writing Process-- the experimental group.

The results of this study Indicated that exposure to the Francis Howell Writing Process did not have a significant impact …

Information Theoretic Analysis Of Multi-Stage Communication/Imaging Systems, William O'Such

Theses

A method for the system analysis of a multistage photographic or communication system is developed. By following the input signal through the system and estimating the output signal and the output signal without noise, the information capacity after each stage can be estimated. The relationship between the variance and the integral of the power spectrum is used in accounting for the effects of each of the component characteristics: modulation transfer function, density-log exposure relationship and granularity. This method is implemented in a computer program which allows one to vary the characteristics of the components and determine the resultant changes in …

An Investigation Of The Affects Of Typefaces Upon Reader's Perception Of The Meanings Of Messages Using The Semantic Differential Testing Technique, Veronica M. Hofman

Theses

This thesis is directed to the area of typography and the affects certain typefaces have on a reader's perception of the message of a text. There have been both empirical and non-empirical studies done that show evidence that connotations and feelings have been associated with typefaces. The intent of this study was to determine the feelings associated with a particular group of typefaces by relating each face to a list of adjective pairs and comparing the results with the content of books which incorporated the face on their jackets. This was to determine whether the content of a book and …

An Evaluation Of The Effect Of Registration On Gcr And Conventional Chromatic Separation Methods In Multicolor Halftone Printing, Chihwe Jeffrey Wang

Theses

Misregistration is an unavoidable problem in multicolor halftone printing. It causes the loss of detail, sharpness and color hue shift of a reproduction. However, there is a color separation technique called Gray Component Replacement (GCR) which may reduce or eliminate this misregistration effect. An investigation had been conducted using a series of color halftone proofs which were produced by conventional chromatic and GCR color separation techniques. The subjective image quality scaling method was applied to this study as a criterion to determine whether there is an image quality relationship between these two techniques on misregistered reproductions.

A Comparison Of The Resolution Obtainable From Photomechanical And Electrostatic Plates, Michael Fitzpatrick

Theses

This thesis addressed the question of what level of resolution was obtainable from the electrostatic plate. Resolution was defined as the ability of a material to record fine detail. Two types of plates were compared, one photomechanical and the other an electrostatic. The photomechanical plate consisted of a light sensitive coating applied to an aluminum1 base . The electrostatic plate consisted of a fused toner image on an aluminum base. The intent of this research was to determine the final resolution, not the forces and factors which effected it. The hypothesis stated that the resulting resolution of the electrostatic plate …

A Model For Non-Image Area Of Offset Lithographic Process, Vinay Chhajlani

Theses

Lithography is the most common printing process. However, very little is known about the theory of lithography. Pressroom practices have evolved more out of experience than on the basis of any theory. The objective of this paper is to develop a mathematical model for the non-image area of the offset lithographic plate. A model of this kind would provide a rationalization for the observed behavior in lithographic process. The study concentrates on the various materials and the phenomena involved. Properties of aluminum oxide surface and gum arabic that make them suitable for the process have been presented. Rheological properties of …

Effects Of Exposure On The Printing Characteristics Of The Association Product Process, Claude David Davis

Theses

The investigation examined the printing characteristics of the association product plate, a continuous tone lithographic process which utilizes a synthetic, light-sensitive coating variably ink-receptive according to the degree of exposure it receives. The methodology was designed to determine (1) the printing range of the plate, (2) the effective sensitivity of the coating to varying amounts of exposure within this range, and (3) the degree to which adherence to ideal tone reproduction could be achieved through systematic variation of exposure. The plate is not commercially available, therefore it was necessary to consult patent literature and prior research to obtain details of …

The Application Of Cie Lab To Study Trapping Efficiency, Patchanee Malikhao

Theses

It has been known that apparent trapping percentages caused by changing printing sequence (or printing order) affect the color appearance of the overprint areas. However, no other studies in the past were done in a standard color measurement system- that is the CIE system. This thesis was conducted in order to learn how the selected printing sequences yellow- magenta-cyan-black, black-cyan-magenta-yellow, yellow-magenta-cyan-black, and cyan-magenta-yellow-black- of a monotack process ink yield the color gamuts on the CIE LAB color space. Since the two sequences: yellow-magenta-cyan-black and cyan-magenta-yellow-black, were recommended to be adopted as standard sequences for SWOP inks, this reseach attempted to …

Vermiculate, Kaolinite, Attacote and Hectorite clays were studied as the sorbent material. Removal of organic pollutants were measured using a total organic carbon analyzer (TOC).

Results indicate that these clays can be used for some treatment of the above mentioned organic compounds. The study shows that removal of organic pollutants by clay depends on several factors, such …

Morphological Analysis Of Microvessels Using High Voltage Electron Microscopy (Hvem), Ibm Personal Computer And 3-D Reconstruction Software, Wieslaw Slawomir Krajewski

Theses

The mesenteric arterioles (outer diameter < 100 µ) from a normotensive and a hypertensive dog were perfused in situ, excised, post-fixed and embedded in Spurr medium block. Thick serial cross sections (0.5 µ) of the vessels were obtained from hand formed mesas and placed on Formvar coated slot grids.

The cross sections were subjected to High Voltage Electron Microscopy (HVEM) and five or more electronmicrographs were taken to cover the individual cross sections. The prints of electronmicrographs were linearly enlarged (3X) and made into photomontages of sections. The membrane contours in the montages were traced on transparent overlays, producing polygons which in turn were traced on GTCO digitizing pad. All polygons were labeled, color coded and stored in IBM PC's filing system. The vessels were reconstructed from up to 100 whole cross sections and subjected to cell compartmentalvolume analysis. The reconstructed images can be …

Optimizing Tone Production On A 300 Spot Per Inch Laser Printer, James R. Hamilton

Theses

Digital halftones as output on plain paper are the focus of this study. A new terminology is suggested to allow proper description of digital halftones. The most important of these terms is the use of "addressability" to replace the often misused term "resolution." Also important is the use of the term "spot" rather than "dot" to describe addressability. A means of properly describing digital halftones is suggested to avoid confusion with analog (ie., conventional photographic) halftones. Halftone patterns were created to test the efficiency of different designs at 300 spot per inch addressability on a laser printer. The page description …

Exploring The Public Administration Of Police/Security Interface, John Richard Carroll Rundel

Theses

Was there a relationship between local police control of private security and tension and misunderstanding between them? Did the above tension and misunderstanding interfere with positive police/ security interface? It was hypothesized that there was a relationship between local police control of private security, tension, and misunderstanding between them which interfered with positive police/security interface.

The central idea of this thesis was : tension and misunderstanding between police/security could be lessened or eliminated by the passage of uniform state legislation. One purpose of this paper was to provide food for thought and further research in contrast to providing definitive answers. …

N-Values And Paper Opacity, Robert Eric Aronson

Theses

The n-value is a factor which allows the Murray-Davies equation to be correctly solved for physical dot area or tint density. This equation becomes known as the Yule-Nielsen equation when the n-value is used.

Many variables affect the value of n; paper characteristics, screen ruling, even the equation variables themselves. The level of solid ink density may have a very significant effect on the n-value. This fact, although suspected, has not been investigated until now.

A study into this variance was undertaken in Appendix II with a method for adjusting the value of n to a standard solid ink density …
