裝璜篇05-45度紙板畫框簡易切割刀技術分享(Decoration 05–Maneuver of 45° Cardboard Cutter) 假期間，如果不外遊 If not travelling during the vacation, 不如自行做一些工藝創作 you may spend your time in art creation 例如書畫剪紙 such as painting or paper-cutting 再將满意的裝裱起來做裝飾 Somehow frame those satisfactory artworks and display them as decoration. 西式視藝作品的裝裱中 In the mounting of Western-style visual artworks, 最普遍的方式是紙板畫框 The most common method is using a cardboard frame. 作品先用裝裱用的膠水裱在2-3mm厚的夾咭上 The artwork is first mounted on a paper cardboard which is 2–3 mm thick using specialized glue. 和中式裝裱托底和裱上夾宣的作用相同 This serves a similar purpose as the backing and mounting paper in Chinese-style mounting. 令作品平直，提高觀賞的感覺 It keeps the artwork flat and enhances its visual appeal. 而且更厚和硬，缺點是不能捲曲收藏 Additionally, it is thicker and stiffer, though the downside is that it cannot be rolled up for storage. 上面再加上一個也是2-3mm厚的顏色紙板畫框 On top of this, a colored cardboard frame, also 2–3 mm thick, is added. 内框4邊用45度切割器切割成斜面 The inner edges of the frame are cut at a 45° angle using a cutter, 加強立體感 which enhances the three-dimensional effect. 邊框的色彩，紋理和寛度也是一種學問 The color, texture, and width of the frame borders are also subjects of study. 紙板是特别為裝裱而製作的 The cardboard used is specially made for mounting pictures. 紙芯要足夠白, 以往只能買入口貨，價錢較貴 Its core must be sufficiently white, making it more expensive. 要到美工專門店購買 and it is typically purchased from art supply stores. 近年内地產的裱咭和切割質素已和西方無異 Recently, the quality of trimmed cardboard made in Mainland China matches that imported from Western countries 甚至能為顧客定制 The workshops accept custom-made orders from overseas 若大量定購，加上包裝運費仍比香港便宜 The unit price for bulk orders can be lower than those offered by local vendors even if the packing and shipment cost is included 美工愛好人士能掌握裝裱, 創作的自由度會更高 Being an amateur artist, mastering the art of framing may enhance one's freedom in the process of creation A3以内的小幅作品 For small artwork within the A3 size 一般按畫芯的長寛比例每邊加4-5cm The frame usually extends 4–5 cm beyond the dimensions of the artwork on each side, maintaining its proportions. 但一些藝術家會將紙框看成作品的一部份 However, some artists consider the cardboard frame as part of the artwork itself, 用多層，多色或特别形狀的紙板畫框來襯托主體創作 using multi-layered, multi-colored, or specially shaped cardboard frames to complement the main creation. 在厚和硬的紙板上開45度斜邊的孔 Cutting a 45° beveled edge on thick, stiff cardboard 理論上需要特别的刀具 Theoretically requires specialized tools. 技术嫻熟的，用普通的＂𠝹刀＂和直尺也能做到 However, those with skilled techniques can achieve this using an ordinary "utility knife" and a straightedge. 在工具矜貴的年代 In times when tools were scarce, 我們參賽或參展的作品裝裱的紙板框便是用普通刀具切割的 The cardboard frames for our competition or exhibition entries were cut using ordinary knives. 市面上的45度切割刀有很多 There are many 45° cutters available on the market, 我們試用過幾款 and we have tested several. 這是我們較愛用的一款 This is one of our preferred models. 双面傾斜刀鋒，推拉都可以 It features double-sided beveled blades, allowing for both push and pull cutting. 能來回切割，也方便左撇子 It supports back-and-forth cutting and is also convenient for left-handed users. 如果第一刀不夠深，補刀較方便 If the first cut is not deep enough, it is easy to make additional cuts. 這些刀具的缺點是刀片在切割時會受力彎曲 The drawback of these tools is that the blade tends to bend under pressure during cutting, 切割線不夠直，我們進行了改裝 resulting in less-than-straight cutting lines. 在刀口上加了膠柱來限制刀片上彎的幅度 To address this, we have modified the tool by adding plastic columns near the blade to limit the upward bending of the blade. 我們習慣在咭面上切割 We usually cut on the surface of the cardboard, 先用鉛筆直尺畫上要開的孔 first marking the desired opening with a pencil and straightedge, 通上少於畫芯5mm-1cm leaving a margin of 5 mm to 1 cm smaller than the artwork. 切割器上有參考線代表切割線 The cutter has reference lines indicating the cutting path, 但不太準確，要憑經驗修正 but they are not entirely accurate and require experience to adjust. 由於45度切割會對切割膠㙯做成嚴重損害 Since 45° cutting can cause significant damage to the cutting mat, 我們用可廢棄的輕膠板或瓦通紙板做㙯片 we use disposable lightweight plastic boards or corrugated cardboard as substitutes. 如果是初次嘗試 For beginners, it is advisable to practice on spare cardboard 先拿一些紙板練習來掌握力度，深度和下刀的位置 to master the force, depth, and positioning of the cut. 厚一點的尺比較安全 A thicker ruler is safer to use. 正常的切割方向是從後方向前方推進 The standard cutting direction is from the back toward the front, 一刀完成 ideally completed in one pass. 這款刀具支援双向切割 This cutter supports bidirectional cutting. 若女生臂力不足 If the user, such as someone with less arm strength, 第一刀只插入一半左右 cannot complete the cut in one go, 在終點將刀鋒再插入紙板直至穿過 they can insert the blade halfway on the first pass, 再拉一刀 then push it through at the endpoint and pull it back for a second cut. 45度紙板框切割是美工設計的基本工 45° cardboard frame cutting is a fundamental skill in art and design. 工多藝熟，直線切割掌握後, 還可以嘗試曲線切割 With practice, one can master straight cuts and even attempt curved cuts. 有機會再跟大家分享 We will share more about this in the future.
