Haath se kaate gaye signature mein hamesha ek hi nishani reh jaati hai: kaagaz ka halka chaukor, jo image ke safed ke alawa kisi bhi cheez par baithne ke saath hi dikh jaata hai. Jawab koi chatur eraser nahin, balki sheet ko naapna hai. Poori tasveer mein khaali kaagaz kitna chamkeela hota — khiDki ke paas zyada, jahan haath rakha tha wahan kam — iska andaza lagaya jaata hai aur ek-ek colour channel se bhaag diya jaata hai, jisse andar ki peeli roshni bhi balance ho jaati hai taaki neeli ink hari taraf na khisak jaaye. Sirf pen bachta hai, narm anti-aliased kinaron ke saath, jinme se kaagaz nikal diya jaata hai — isliye rangeen page par koi fringe nahin jaata. Phir use trim kijiye, patli ballpoint line mote kijiye, padding dijiye aur height chuniye. Tasveer paDhi jaati hai aur PNG aapke device par likhi jaati hai.

Common errors aur troubleshooting
Signature mein sleti patches aa gaye. — Pencil ya lagbhag sookha pen chamak mein kaagaz ke bahut kareeb hota hai. Pehle sensitivity baDhaiye; patches phir bhi rahein to gehre pen se dobara sign kijiye — ek hi shade ki ink aur kaagaz ko koi alag nahin kar sakta.
Stroke tooT kar dotted line ban gayi. — Dhabbe ka size kam kijiye — setting se chhote tukDe dhool maan kar hata diye ja rahe hain. Tez chalti ballpoint aksar skip karti hai, isliye aadha pixel mota karne se wo wapas juD jaati hai.
Yahan theek dikhta hai par document mein safed box aa jaata hai. — Beech mein kabhi file JPEG ban gayi, aur JPEG transparency rakh nahin sakta. Document tak use PNG hi rakhiye.
Kinare narm nahin, kaTe-kaTe aur seeDhinuma hain. — Tasveer pehle se hi black and white thi. Fax ya one-bit scan mein grey levels hote hi nahin jinse narm kinara ban sake — greyscale ya colour mein dobara scan kijiye.
Aksar pooche jaane wale sawaal
Haath se kaata signature rangeen page par sleti box kyun dikhata hai?
Kyunki us cut-out mein ab bhi kaagaz baaki hai. Jo edge pixels safed lagte hain wo bhi ink aur sheet ka mishran hote hain, aur rang par wo mishran halo ki tarah paDhta hai. Kaagaz ko naapkar un pixels se nikaal dena hi use rokta hai.
Signature ki photo lena behtar hai ya scan karna?
Dono chalte hain. Scan zyada flat hota hai aur kam sudhaar maangta hai; barabar din ki roshni mein phone se li photo bhi theek hai, kyunki sheet par ki roshni ka andaza lagakar use bhaag diya jaata hai. Flash se bachiye, wo chamkeela dhabba chhoD deta hai.
Kya signature ki image kanooni roop se maanya signature gini jaati hai?
Yeh poori tarah document aur us jagah ke kanoon par depend karta hai, aur yeh tool iske baare mein koi daava nahin karta. Bahut se agreement chipkai gayi image maan lete hain; kuch certificate-based digital signature maangte hain. Dekhiye document kya maang raha hai.
Email footer ke liye signature ka size kya hona chahiye?
Lagbhag 150 px oonchai aam hai — paDhne layak baDi, par footer par chhaa jaane layak nahin. Aap jo height chunte hain usme padding shaamil hoti hai, isliye 150 px ka chunaav sach mein 150 px ki file deta hai.
Apne hi signature ke strokes mote karne ki zaroorat kyun paDegi?
Kam resolution par scan ki gayi baareek ballpoint ek-pixel ki line ban jaati hai jo screen par lagbhag gayab ho jaati hai aur print mein nikal jaati hai. Aadha pixel ki motaai aksar itni hi kaafi hoti hai ki wo phir ink jaisi lage.
