Abstract

Disertacija proširuje i otvara novi pristup kreiranja tipografije u sigurnosnoj grafici.

Tijekom više godina istraživanja uoceno je da ovakva tema nije obradivana i

prezentirana preko stohastickog pristupa. Pokazala se potreba za uvodenjem

vlastitih programskih rješenja izvedenih unutar PostScript jezika na mutacijskoj

tipografiji. Prezentirani su fontovi nastali upotrebom digitalnih alata i njihova upotreba

u zaštitnoj tipografiji. Projektira se mutacija novih fontova na vrijednosnicama i

dokumentima. Mutacije su izvedene provlacenjem tekstova kroz unaprijed stvorene

programe. U radu se prezentiraju gradacije svjetline tonova pismovnog reza

izvedenih u mikrotipografiji. Osim zaštitnih svojstava mikrotipografija nudi i

individualna dizajnerska rješenja.

Predstavljeni su novi rasterski elementi cija upotreba je omogucena razvojem

digitalnog tiska. Stohasticki pristup i stvaranje generatora slucajnih brojeva omogucio

je kreiranje zaštitnih tipografskih rješenja baziranih na pseudoslucajnom izboru

rasterskih elemenata, linijature i kutova rastera. Uvodi se i rastriranje pomocu

originalno projektiranih oblika rasterskih elemenata - slovnih znakova. Kreirani su

piktogrami u obliku slovnih znakova, te u svrhe kreiranja posebno oblikovanih

rasterskih elemenata. Na njima su provedena mjerenja pokrivenosti svih znakova

pojedinih fontova, te su uspješno korišteni kao rasterski elementi stvarajuci

reprodukcije na nov nacin. Izvedene su programske deformacije piksela koje

omogucuju dodatnu zaštitu prilikom pokušaja krivotvorenja vrijednosnica. Upotrebom

nekoliko razlicitih generatora slucajnih brojeva postiže se potpuna nezavisnost

pojedinih parametara u programima i poboljšavaju se zaštitna svojstva takvih

rješenja.

Dokazane su prednosti tipografije nad linijskom grafikom u podrucju zaštite

dokumenata. Prilikom istraživanja se ušlo u grafiku za infracrveni dio spektra kako bi

se istražile mogucnosti stvaranja zaštitne tipografske informacije u tom podrucju.

Razvojem uredaja, instrumenata i alata proširuju se mogucnosti krivotvorenja

vrijednosnica pa je potreba za novim sigurnosnim elementima i oblicima zaštite

narocito izražena.

Abstract (english)

This dissertation widens the range and opens a new approach to creating typography

in security graphics. During several years of research it has been noticed that this

subject has not been yet elaborated or presented through the stochastic approach.

There was a need to introduce one's own program solutions carried out within the

Post Script language on mutational typography. Fonts that were created by using

digital tools are presented here as well as their use in security typography. Mutation

of new fonts is being designed in securities and documents. The mutations are

carried out by having texts go through programs created in advance. The paper

presents gradation of the letter cut shade brightness carried out in micro typography.

Besides offering security properties, micro typography also offers individual design

solutions.

New screening elements are introduced, the use of which is made possible with the

development of digital printing. The stochastic approach and creating of random

number generators have made it possible to create security typographic designs

based on pseudo random screening element, liniature and screening angle choice.

Screening with the help of originally designed screening element forms – alphabetic

characters is also introduced. Pictograms in the form of characters have been

designed with the goal of creating specially formed screening elements.

Measurements have been made as to the covering capacity of all characters

belonging to some fonts, and they have been successfully used as screening

elements that produce reproductions in a new manner. Pixel program deformations

were carried out that provide additional protection against efforts to counterfeit

securities. With the use of several different random number generators, complete

independence of certain parameters in the programs is achieved, and the security

characteristics of such solutions are improved.

The advantages of typography over linear graphics are proven in the area of

document security. During research work the area of graphics linked with the infrared spectre area has also been entered in order to investigate the possibilities in creating

security typographic information in this area too.

With the development of device, instruments and tools the possibilities of security

counterfeiting are growing, so the need for new security elements and forms of

protection is especially pronounced.
