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 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 …

Synthesis And Characterization Of A Novel Blocked Isocyanate Dental Adhesive Based On Diphenylmethane - 4, 4' - Diisocyanate, Yangming Lin

Theses

The dental adhesive monomers based on diphenylmethane - 4,4 - diisocyanate (MDI) were prepared and studied in this research. The diisocyanate, MDI, was first reacted with hydroxyethyl methacrylate (HEMA) to form an intermediate adduct. This adduct had an active isocyanate end group. It was then bonded with o-chlorophenol (OCP), a blocking agent, to produce a blocked isocyanate monomer.

The new blocked isocyanate (HEMA-MDI-OCP) was found to have an average value of more than 1200 psi in tensile tests measuring its adhesion to dentin slices.

The Switch Capacitor Biquad Filter And It's Application On Active Filter Design, Sung-Chiang Chang

Theses

The purpose of this subject is to use the programmable switch capacitor filter to design a traditional analog filter which usually cause a tedious job on finding a group of values for resistors and capacitors. We start from the basic concept of switch capacitor, then we learn to use auxiliary equipment to design a filter. To design the desired filter, first, we have to find the s-domain transfer function, then transfer it to the z-domain. After we found the coefficients of z-domain transfer function, we have to implement this on the auxiliary equipment. Then we will get the desired filter.
