Com cada any els alumnes de segon cicle de SIEI estem participant en un projecte eTwinning amb alumnes d’un centre de les A\u00e7ores (Portugal). Enguany el projecte t\u00e9 per t\u00edtol: LET’S STUDY ENGLISH!; un dels apartats s’anomena: ARTS AND CRAFTS.<\/p>\n

Volem fer el disseny d’una samarreta conjuntament amb els nostres companys portuguesos i calia saber primer com es duu a terme aquest proc\u00e9s d’estampaci\u00f3. Per aix\u00f2 hem visitat una tenda-taller de serigrafia que hi ha a Ulldecona (Tecnoprevent), on Gerard (el seu propietari) ens ha ensenyat aquesta t\u00e8cnica.<\/p>\n

En primer lloc, cal dir que la serigrafia \u00e9s un procediment d’estampaci\u00f3 sense relleu que consisteix a transferir tinta a trav\u00e9s d’una gasa tibada en un marc o bastidor. S’han d’obturar amb emulsi\u00f3 fotosensible les parts on no es vol deixar passar tinta. La gasa mostra un aspecte de negatiu del que acabar\u00e0 sent l’estampa. Es col\u00b7loca la pantalla serigr\u00e0fica damunt del suport a imprimir i es fa passar la tinta a trav\u00e9s de la gasa, aplicant-li una pressi\u00f3 moderada amb un corr\u00f3 o una rasqueta de cautx\u00fa. Pot imprimir-se sobre gran quantitat de materials, normalment a trav\u00e9s d’un teixit por\u00f3s.<\/p>\n

Tamb\u00e9 hem vist com es fa aquest proc\u00e9s amb l\u00e0mines d’estampaci\u00f3 en calent. Es fa servir una l\u00e0mina que t\u00e9 el dibuix en negatiu, de manera que quan se li aplica calor a sobre (vora els 200 \u00ba C) el deixa pegat a la superf\u00edcie que es vol estampar.<\/p>\n

Per finalitzar la visita, Gerard ens ha deixat estampar uns tapaboques que ens ha regalat. Hem posat el dibuix d’un ull. Reconeixeu el disseny?, alguna idea de a qui pot pert\u00e0nyer? Us donem una pista, pertanyen a uns dibuixos animats molt c\u00f2mics.<\/p>\n

Tamb\u00e9 ens ha lliurat una bossa de cord\u00f3, tipus motxilla. Des d’aqu\u00ed volem agrair a Gerard les seves explicacions i el taller d’estampaci\u00f3 que hem fet amb ell. Ara ens queda molt m\u00e9s clar com es posen aquests dibuixos i la dificultat que implica el canvi de text, color, etc. De ben segur que ho tindrem en compte a l’hora de dissenyar la samarreta amb l’EBI de Praia da Vit\u00f3ria (A\u00e7ores).<\/p>\n","protected":false},"excerpt":{"rendered":"
