Queste fessure sono evidenti sia sulla superficie della matrice che sul prodotto stampato.<br>Questo caso particolare \u00e8 successo in uno stabilimento di stampa diretta su cartone ondulato con inchiostri a base acqua.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gli inchiostri a base acqua sono caratterizzati dalla presenza di di ammine nella formulazione e hanno un valore di pH piuttosto alto (~8,5\u00f79,5). Queste caratteristiche tendono a indebolire la superficie del clich\u00e9 dopo un contatto prolungato.<br>In questo caso la matrice non \u00e8 stata adeguatamente pulita dopo la stampa e l&#8217;inchiostro \u00e8 stato lasciato seccare sulla superficie.<br>L&#8217;inchiostro subisce un leggero restringimento durante l&#8217;asciugatura e questo ha creato una tensione sulla superficie stampante della lastra che si \u00e8 screpolata.<br>Successive attivit\u00e0 e ristampe hanno peggiorato il problema.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pulire sempre le lastre dopo la stampa
