A cria\u00e7\u00e3o de composi\u00e7\u00f5es no SpectraProof \u00e9 muito simples: qualquer material pode ser digitalizado ou fotografado e, em seguida, guardado como um ficheiro JPEG com um perfil ICC, como o ProFotoRGB, associado, devendo o perfil RGB ser id\u00eantico ao espa\u00e7o de cor de trabalho interno. Estas imagens s\u00e3o armazenadas em diferentes pastas no SpectraProof. Os materiais ficam ent\u00e3o dispon\u00edveis na lista de sele\u00e7\u00e3o de Substratos, por exemplo, se estiverem na pasta Substratos.<\/p>\n\n\n

Por que esta simula\u00e7\u00e3o \u00e9 t\u00e3o importante? Por exemplo, quando a simula\u00e7\u00e3o de papel \u00e9 ativada na prova de perfis ICC cl\u00e1ssica, o resultado \u00e9 simplesmente uma \u00e1rea de cor desenhada no fundo. Isto pode funcionar bem para papel de c\u00f3pia ou papel contendo OBA. A superf\u00edcie do papel na prova digital ter\u00e1 um tom azulado, cor de camur\u00e7a ou cinzento.
A pr\u00e9-visualiza\u00e7\u00e3o em ecr\u00e3 falha com pap\u00e9is como o de jornal, papel\u00e3o, kraft e pap\u00e9is com inclus\u00f5es de efeito. A pr\u00e9-visualiza\u00e7\u00e3o em ecr\u00e3 produz apenas uma superf\u00edcie monocrom\u00e1tica que pouco tem a ver com a apar\u00eancia real do material. Talvez o valor LAB esteja correto, mas a estrutura, o toque, a impress\u00e3o e as inclus\u00f5es est\u00e3o em falta. Um tom suave de cinzento parece simplesmente artificial e, na maioria dos casos, definitivamente incorreto.<\/p>\n\n\n\n

Nem mesmo os nossos olhos conseguem compensar isto. Em alguns casos, os fabricantes de provas desenvolveram pap\u00e9is de prova que simulam estes tipos de papel. \u00c9 o caso do papel de jornal, por exemplo. Porque mesmo que se imprima apenas a simula\u00e7\u00e3o de papel para papel de jornal na prova, ainda assim parece um pouco artificial.<\/p>\n\n\n\n

O SpectraProof melhora este processo desativando a simula\u00e7\u00e3o de papel e, em vez disso, sobrepondo uma renderiza\u00e7\u00e3o realista \u00e0 prova digital. O substrato ou a folha met\u00e1lica \u00e9 aplicado em todo o fundo. No caso de uma folha met\u00e1lica a quente como material de revestimento, s\u00e3o utilizadas superf\u00edcies met\u00e1licas digitalizadas, tais como ouro, prata, vermelho met\u00e1lico e verde met\u00e1lico. Uma separa\u00e7\u00e3o no SpectraProof pode ent\u00e3o ser ativada e definida como \u201cfolha\u201d com um simples clique num bot\u00e3o. O utilizador pode ent\u00e3o selecionar o material a utilizar para a simula\u00e7\u00e3o da folha nos par\u00e2metros de composi\u00e7\u00e3o.<\/p>\n\n\n\n

O SpectraProof utiliza essas composi\u00e7\u00f5es fotogr\u00e1ficas com as respetivas informa\u00e7\u00f5es de p\u00edxeis provenientes da separa\u00e7\u00e3o e coloca ali a imagem fotorrealista da folha met\u00e1lica. Isto funciona exatamente da mesma forma que o processo na produ\u00e7\u00e3o de impress\u00e3o. Aqui, \u00e9 criado um filme e, em seguida, um clich\u00e9 de grava\u00e7\u00e3o, sendo que a folha a quente \u00e9 gravada exatamente onde o clich\u00e9 a posicionou. A SpectraProof funciona exatamente da mesma forma no monitor, utilizando a separa\u00e7\u00e3o como m\u00e1scara para incorporar a digitaliza\u00e7\u00e3o do material no clich\u00e9 em conformidade.<\/p>\n\n\n\n

Esta situa\u00e7\u00e3o \u00e9 ligeiramente diferente na simula\u00e7\u00e3o de laminados, uma vez que o laminado altera a impress\u00e3o e a cor da mesma. Por conseguinte, o SpectraProof sobrep\u00f5e uma camada \u00e0 prova digital para simular o laminado e o verniz.
A lamina\u00e7\u00e3o mate clareia as \u00e1reas escuras da impress\u00e3o e cria uma esp\u00e9cie de branco difuso, formando uma esp\u00e9cie de v\u00e9u sobre a imagem. Com a lamina\u00e7\u00e3o com pel\u00edcula brilhante, tudo tende a escurecer e fica com maior contraste e nitidez. O SpectraProof consegue esta simula\u00e7\u00e3o de cor colocando p\u00edxeis de cor sobre a prova digital. O utilizador pode definir um valor de opacidade ou cobertura para esses p\u00edxeis.<\/p>\n\n\n\n
