계산값이랑 실제 종이값이 2mm정도 차이가 나더라구요. 확인 후 수정 부탁드려요~!

**Developer response:** 안녕하세요, 자세히 확인 후 개선하도록 하겠습니다. 소중한 제보에 감사드립니다. 혹 괜찮으시다면 계산하신 계산값과 실제 종이값 정보를 guhochoi.works@gmail.com 으로 보내주시면 보다 정확하게 확인, 개선하는 데 더 큰 도움이 될 것 같습니다. 대단히 감사합니다.

### 5/5 — 용지선택 항목

*2021-10-09*

1.용지선택 항목에 대국전 (720*1020)사이즈도 추가하면 좋을듯 합니다 카렌더 제작시 많이 쓰이는 사이즈입니다

2.낱장 소요량 계산에서 4*6전지 4절(359*545)
2,000부면 1R이 소요되는데 2R으로 표기되는데 확인부탁드립니다

**Developer response:** 대국전지(720 x 1020 mm) 사이즈를 새 업데이트를 통해 추가하였습니다. 소중한 의견 주셔서 감사합니다. 2번 문의해주신 사항은 확인한 결과, 물림몫(앱 기본값 10mm)과 인쇄 도련 값(앱 기본값 3mm)을 모두 0mm로 설정 후 계산하시면 횡목 기준 1R이 나오는 것을 확인하실 수 있습니다. 문의해주셔서 감사드리며 답변이 충분치 않은 경우 페이퍼맨 앱의 ‘정보’ -> ‘개발자에게 이메일’을 통해 추가 문의 부탁드립니다. 감사합니다! :)
