Variando l\u2019intensit\u00e0 di ciascuna componente si possono ottenere fino a 16,8 milioni di tonalit\u00e0 diverse. Essendo i colori fondamentali della luce, l\u2019RGB \u00e8 alla base di tutte le rappresentazioni digitali: ogni immagine visualizzata su uno schermo \u2013 dal monitor del computer allo smartphone, fino alle foto scattate con una fotocamera digitale \u2013 utilizza questo spazio colore. Si tratta di un modello additivo: i colori non derivano da pigmenti ma dalla combinazione della luce. Pi\u00f9 luce viene aggiunta, pi\u00f9 l\u2019immagine appare chiara.

Questi inchiostri vengono stampati (in genere) su un fondo bianco. Nel modello sottrattivo vale la regola opposta rispetto all\u2019RGB: pi\u00f9 colore viene applicato, pi\u00f9 scura risulta l\u2019immagine. La presenza del nero \u00e8 fondamentale, perch\u00e9 al 100% di Ciano, Magenta e Giallo non si ottiene un nero profondo, ma soltanto un marrone molto scuro. Il CMYK \u00e8 lo standard utilizzato nella stampa offset \u2013 la stessa tecnologia dei comuni stampanti domestiche \u2013 ed \u00e8 naturalmente il sistema di riferimento anche nella stampa online. Le quattro tinte vengono applicate in sequenza sul foglio e, grazie alle diverse combinazioni, danno vita a un\u2019ampia gamma cromatica. In teoria, nello spazio colore CMYK si potrebbero generare oltre 4 miliardi di colori, ma sia sullo schermo sia in fase di stampa il numero effettivo \u00e8 molto inferiore. <\/span>Di fatto, il gamut del CMYK \u00e8 pi\u00f9 ridotto rispetto a quello dell\u2019RGB.<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text]\n

Convertire da RGB a CMYK per la stampa<\/b><\/h2>\n

Ed \u00e8 proprio qui che nasce la sfida nella preparazione dei file di stampa: foto, immagini ed elementi grafici sono quasi sempre in RGB e devono essere convertiti in CMYK per poter essere stampati. Poich\u00e9 non tutti i colori possono essere riprodotti in maniera identica, durante la conversione possono verificarsi variazioni cromatiche. Per evitare sorprese, \u00e8 sempre consigliato lavorare direttamente in CMYK:<\/span><\/p>\n
